Seishun Buta Yarou wa Yumemiru Shoujo no Yume wo Minai

I felt like I was watching Suzumiya movie. Very similar plot.  

Let's get one thing straight The Disappearance is a masterpiece, no anime sequel film has ever or likely will ever touch the level of quality that it delivers. However, I get why people compare these two, they do have a similar tone, similar characters. If you want something like The Disappearance, you could do worse than this one.  

if you're a spinoff movie for a popular science fiction/slice of life/dramedy anime series about emotional high schoolers dealing with supernatural events and your plot relies heavily on time travel paradoxes raise your hand  

First off, both movies/series are a must watch. If you haven't seen one of these add them to your watch list immediately. (bunny senpai movie is available to watch outside of cinemas as of a few weeks ago) the Suzumiya movie is widely regarded as a masterpiece and struck the attention of many anime fans when it was released. The fan base were largely skeptical about the previous season but were blown away by how well crafted the movie turned out. Bunny girl senpai gives off a very similar vibe, it's quiet, understated and slow-building but goes from 1-100 very quick. The movie struck me in the same way Suzumiya did all those years ago. Trust me, if you've been putting either of these shows off or haven't yet watched the movies you should go do it right now. read more 

Both Anime have a very similar, dark tone and atmosphere. The plot is also suprisingly similar to the point where a complete coincidence is hard to believe, having the Main Character try to save the ones he loves alone without any idea how to. And even if I think Haruhi Suzumiya is far better at almost every level, everyone should check out both movies if they are interested. 

-They share a very similar plot - Time travel by the characters in order to change something in their relative present -Both serve as a sequel movie to a pretty good TV series -Very similar vibes from the both of them, so give it a go... You might enjoy it :) 

Both movies have a similiar feel to it: -Both are based in time travel; -Both female leads get forgotten by everyone; but when everything's over, they regain their memories of the dearest ones; -Seishun buta yarou has more romance, whilst in "The Disappearence of Haruhi" it is focused more in suspense/Mystery. Nonetheless, Really great shows! 

Since Steins;Gate is way more known, i'll just say that I definetly felt a Steins;Gate vibe in Seishun Buta Yarou wa Yumemiru Shoujo no Yume wo Minai Movie, the first season of Buta Yarou must be watched before the movie ^^ If you haven't seen Steins;Gate, just go watch it 

Plot is related to time and there is romance involved in both. 

-Both of them share a similar back-drop - Going to different timelines to change or alter the protagonist's relative present -Some scenes will leave you in denial, which is a good thing when watching a show of this sort -If you enjoyed the premise of either, you'll enjoy the other show too :)  

It has a very similar plot line with a main character having to use time travel to save the people he cares about. Similar themes of grief and dealing with loss are touched on. Keep in mind this is a sequel and requires watching the original series. 

Both of these anime have the main character wondering to themselves which of two people they must save. They know that even if they manage to save one person, it's painful to lose the other, and they must find some way to save both of them. This can include making decisions that have big risks, losing memories, and possibly not meeting someone in the first place. They will do whatever it takes to make sure that everyone is happy in the end. 

Without spoiling steins gate, both shows have a main character while fully being aware of the weird things that have been happening around them, they both have a female figure that supports them throughout the series, and especially in the movie they both delve into the theme of time travel o alter a tragic future... 

Both contain similar themes of trying to go back to do something. 

-Both of these movies involve the use of time-travel, so as to change a certain outcome in the protagonist's relative present -They share the same 'Romance' tag, and rightfully so. All my fellow romance lovers out there will enjoy the levels in both (Do note though, that you'll need to have watched the original TV series for 'AoButa' for the movie to make any sense whatsoever) 

- Similar style. - Almost same genres. - Both movies are very emotional. 

Similar story progression. Remember what made Kimi no Na wa interesting when you watched it. An above-average anime that evolves into a masterpiece, right? Bunny Girl's series was the above-average anime part. This movie, the sequel of Bunny Girl is the masterpiece part. Other than that, things are similar genre-wise. You'll probably think of both in a similar way. 

These anime are related to time, creating the same environment as the protagonists of trying to find a suitable solution. Both are sentimental and fun that allows satisfaction when seeing it. 

*Note* Both movies require prior knowledge of their respective shows. That said, if you enjoyed both of these shows and either want more, or you've seen one of these movies and not the other, then I highly recommend watching these movies. Both are decent quality objectively, and if you enjoyed the anime, then subjectively they're high quality for enjoyment purposes. They have a similar feel and flow to them. In the end, I walked away from each movie feeling satisfied and with the proper amount of feels and closure from a movie sequel.  

Plot twist in the middle was very similar to the twist in 'pancreas'. Also some cocepts of story were alike 

Both has similar plots. The protagonist trying to rescue people close to him while traveling back in time and not having full control of the ability. Also the element of surprise is really there in erased. If you like one, you'll definitely like the other. 

Similar plot points, development, MCs, and MC relationships, and supernaturals. Watching this really reminded me of after story. After story does have a lot more drama, while dreaming girl has more time time travelling stuff.
