In Beyond the Infinite Two Minutes they have a window into the future, time in constantly moving forwards but they can see two minutes ahead, giving them the opportunity to receive communication from their future selves. In River time keeps resetting, so everyone jumps back to the point in space and time they were at 2 minutes ago but they retain the knowledge they accrued in the last two minutes. It makes it more like an escape room puzzle as they try to understand what is happening and why, and figure out a way to break the loop. There are obvious comparisons to Groundhog Day in the premise, but it's quite different given the tight timing and that everyone in the town is experiencing the same thing, not just our lead character. The filmmakers wanted to spring off from the same 2 minute constraint as their previous film but go in a completely different direction. Where in BTITM it (appears to) take place in a single shot, here every 2 minute section of the time loop is a single shot. They start in the same place but go somewhere different, and it's great fun seeing how they choreograph all that and tell the different stories of all the people at the inn within the limitation they set themselves. It's definitely not a remake, and is a really lovely film.

So I watched it finally, quite enjoyable, actually probably more than the first movie, quite funny, though didn't like the ending and that they didn't get away during 2 minutes to escape the loop.

This should be renamed to Groundhog Two Minutes, which would describe the movie pretty well.
