Surprisingly watchable and entertaining. Good actors and the production feels professional and well done, although on a low budget side. In any case the movie has a very nice sci-fi idea which contrary to a time travel is much more plausible and under-explored in Hollywood. So it is nice someone decided to give the multiverse a shot, besides Rick and Morty, but unfortunately they decided to focus more on sentimental side of the characters instead of the hard sci-fi aspect of it. So as result the movie focuses more on moral and emotional dilemmas and consequences, how far will people go with the power they've been given, instead of a dive into a sci-fi complications of their discovery. In short, if to compare it to time travel genre, this movie is trying to be more The Butterfly Effect and less Primer, for example. It's an easier choice but the world they created seems underexplored and focuses on smaller picture as result. Maybe someone will continue with that idea to a TV show with more screen time for a proper exploration of the concept.
