Whoever reviewed this and called it "repetitive" does a disservice to the movie.. I personally would call it anything but!

You have a simple structure that expectedly raises the stakes of using a "time machine" for personal purposes, specially when the effects are as impactful. There's no buildup, but it is more "revelative" as it develops. It does become predictable, though. It's also a tad too long, the pacing is somewhat slow in many parts, and lacks in engagement. But I can't see it ending in any other way, as it accomplishes what it sets out to do.

If it raises any questions, they are for the viewer to ponder, as the movie isn't interested in saying anything else nor has the room for it. And if the film's budget is preventing you from enjoying the story, then you probably shouldn't be looking at low-budget sci-fi.

I would compare this to a Black Mirror episode, and was enjoyable as such.
