I'm getting so sick of the whole day-keeps-repeating-over-and-over plot line. No movies that I know of have really done anything new with the concept, but they at least manage some sense of charm and intrigue. Unfortunately, the painfully generic Map of Tiny Perfect Things flounders in that department.
The story is pretty much exactly what you'd expect. It's so predictable, that it's entirely unnecessary to put it in this review. Just read the basic premise and title, and you've already got a pretty good idea as to where it's going.
Now, that on its own wouldn't be a problem. The similarly predictable Palm Springs managed to be incredibly enjoyable, thanks to great performances, some funny lines, and solid writing. The Map of Tiny Perfect Things is just... meh in every department. The performances are serviceable, but they aren't exceptional. The writing does okay, but there's really nothing memorable. And there is but one funny line in the entire movie, which inexplicably is said in the middle of what I assume was supposed to be an emotional scene.
Additionally, the whole film has an aggressive Indie vibe, as if every frame is screaming "WE WEREN'T MADE BY A BIG MOVIE STUDIO." This is especially strange, considering that it was made by Amazon, one of the largest companies in the world. Because of this, the whole film has this underlying sense of corporate control that was almost a little eerie. For example, it feels like the love interest has a sad backstory not so that the audience can empathize with her, but rather because the studio heads say it'll make people cry. Honestly, this strange tone persisted throughout the movie, and I was more than a little uncomfortable with it.
Overall, the Map of Tiny Perfect Things is harmless and doesn't really have anything horrible in it. Items just so cookie-cutter and bland, taking an overdone premise and doing nothing new with it. I suppose it will make for a serviceable movie-watching experience, but frankly there are much better time travel movies out there (Safety Not Guaranteed on Netflix, Palm Springs on Hulu, and Donnie Darko come to mind). The Map of Tiny Perfect Things isn't a horrible way to spend 90 minutes, but I'm sure most people will have much better things to do with their time.
