Okay, so that person you're in deep, denial-y love with suddenly disappears! What do you do!? Risk screwing everything over in a crazy attempt to get them back? Or (snrk) just accept a world without them? Questions both asked and answered by these two absolutely wonderful movies, both of which provide some good closure to their respective preceding TV series.
Movie sequels which have more psychological aspect than the series. There's also many similarity such as tsundere MC, parallel world, time travel, time loop and suddenly-vanishing-MC. Also have outstanding visuals and music.
Both Suzumiya Haruhi no Shoushitsu and Steins Gate: Fuka Ryoiki no Deja Vu borrow their basic plot-line from the same common source material: Kimagure Orange Road, which was a popular anime TV series in the '80s.
In all three anime, the protagonist somehow goes back in time to when they were kids, but by doing so this causes serious ramifications for the future, a future where the existence of their loved one is endangered, so the protagonist must try to fix things back to normal. Along the way, the protagonist meets and leaves a strong impression on a kid who turns out to be someone they know in the future.  read more
Both movie includes a package of time traveling phenomenon, supernatural elements, and character relationships.
There is mystery involved in both movies as the character tries to figure out the events that occurs in their perspective worlds. More so, they also try to solve their problems that comes as no easy task. There is comedy present in both movies in the form of dialogues and character interactions. At the same, emotional moments are factored in that balances the lighthearted and melancholic tones.
Apart apart from the obvious similarities of these 2 movies being sci-fi and serving as conclusive endings to the series, they are both brilliantly executed. And while it's quite surprising how unexpectedly similar even the plot lines are, they both retain their originality.
However, unlike the Steins;Gate movie (which has a brilliant, unparalleled series preceding it), the Haruhi Suzumiya movie actually surpasses its original series.
Both are highly recommended! (must watch series first)
Aside from both are movie sequels of two popular anime,
- focuses on a situation where a main character (from the original story) does not exist or had his/her existence modified.
- then they do everything to restore what has been "normal" before by means of time traveling.
- also revealed the origin of intriguing names. Hououin Kyouma and John Smith.
The two are Movie SEQUELS of their respective TV series counterparts and both have somebody who suddenly disappears. Both have somebody who tries to find the missing person. And avoid the disappearance. They have a sense of romance in the movie.These also contain some comedy. Both are a somewhat serious type of Movie.
Both movies are incredibly good.
Both movies deal with the aspect of a main character "disappearing" and the emotional trauma that follows.
To truly appreciate these movies you have to have seen the anime shows.
If you like Haruhi Suzumiya or Steins;Gate you will love their movies.
Both have same background story. However steins:gate giving more detail about their story on their series so its more make sense than Kumo no Mukou.
If we talk about romance , of course Steins;gate is no match for makoto shinkai. But if we talk which one is more entertain, Steins;gate is the winner
I suggest Steins;gate deja vu movie because the story was close enough with Kumo no Mukou but of course you need to watch the series for more detail.
Steins;Gate: Fuka Ryouiki no Déjà vu appears to have been influenced by Kimagure Orange Road in various ways. They both use some similar time-travel plot elements, as well as alluding to parallel universes and having a sort-of-tsundere female lead.
The last few episodes of Kimagure in particular has a similar plot:
*SPOILER* The protagonist's time-travel to the past causes ripple effects in the future which he needs to fix, and along the way he meets a younger version of someone he knows. */SPOILER*
The Disappearance of Haruhi Suzumiya was also influenced by Kimagure Orange Road, which explains some of the similarities between the Haruhi Suzumiya and Steins Gate movies.  read more
