Natsu e no Tunnel, Sayonara no Deguchi

Kaoru Touno's family is falling apart. After the death of a sibling and his parents' divorce, he no longer feels any peace at home. Following a heated confrontation with his father, Kaoru runs out of his house and finds himself before a mysterious tunnel, which pulls him in. Bewildered by what he sees inside, he rushes to the exit, picking up a bird that looks identical to his deceased pet on his way out.

Upon emerging outside, Kaoru realizes that, despite him spending just a few minutes inside the tunnel, an entire week has passed. The bizarre experience leads him to remember the rumors of "Urashima Tunnel"—a passage that grants wishes in exchange for one's lifespan. Given the resurrection of his pet bird, Kaoru cannot help but wonder if another visit can help fix his messed up life.

However, when he returns to the entrance of the mysterious tunnel, Kaoru realizes that he has been followed by Anzu Hanashiro, a new transfer student in his class. She also knows about the rumors and asks him to help her with an experiment—it turns out that she, too, has a wish that only the tunnel can grant.

While people may complain about the overall pacing of this adaptation I think this movie is incredibly well done for the amount of time it had. I think it might have been better in anime format with a season or two but I feel like we would have lost a LOT of the quality that made this movie so beautiful. The colors were vibrant, the emotion in both dub and sub were raw, and the struggle is real. so overall while you might not like the pacing of it, the story still stands on its own two feet with a supernatural, psychological & romantic twist ... that you just don't see in a lot of films! I have ALWAYS loved when they take a supernatural element and mix in a bit of romance. So this series was right up my alley. If you are looking for something that has similar supernatural vibes to SummerTime Rendering with Romantic vibes from SNAFU then I recommend you watch The Tunnel to Summer, the Exit of Goodbyes!

Mixed Feelings

Its just alright really. The Tunnel to Summer has such a melancholic and angsty vibe its almost hard to take seriously in parts. Most of the characters are void of personality and any kind of interesting traits. It seems as though Taguchi aimed to create almost an entirely bleak atmosphere throughout the duration. This does contrast well with the scenes in the Tunnel which are stunningly beautiful. My main problem with this movie is how cliche and generic the main characters plot line is leaving him a very uncompelling and boring presence. It's abundantly clear that this was written to tell Anzu's story and it ... doesn't even try to hide that. Anzu's story was clearly the highlight, reminding me somewhat of John Keats in his actual life. Conversations over artistic insecurity and legacy are easily the standout philosophical elements of the movie, most of the rest is just B-grade teenage angst. Overall nothing special at all, little to remember this by save a few scenes. I will say that the scene of the two mains in the bedroom is very good and the highlight of the show in every way possible, a series of truly beautiful sequences that leaves me wanting so much more that the final third is totally unable to capture. Overall just an okay movie, nothing overly offensive and little unique worth a watch simply for its short runtime.

Amazing and very creative plot, but in my opinion read the light novel instead

The movie feels really rushed and somewhat incomplete, and there were very annoying potholes in the end and the ending wasn't well written, as a standalone it is worth watching, but it is better in my opinion to read the light novel instead if you don't despise reading. You will be missing out on the great soundtrack and animation, but the lacking plot in the movie makes the choice clear in my opinion, read the light novel.

However the movie is still good, but again, I couldn't ... tell you to favor watching the movie over reading the light novel if you enjoy reading.
