So, I don't even know where to start here. This movie... Was surprisingly fun to watch. In no way was it good, it was so bad it was good. Think Gremlins but with crabs and a little less serious. Visual effects are nothing to bra about but luckily the creators decided to go more practical than visual using suits and minimal CGI. There are a few questionable moments though where you wonder why? Why did they use CGI here when practical would have been better, easier and probably cheaper.
Sound effects and music are spot on. The sound effects are funny, especially the sounds and noises the crabs make, at first you wonder "WHAT!?", but after a while you more like "Ooooh, that's funny".
But, besides that, this movie delivers. The acting is actually not that bad except for a few characters where the actor(s), which are probably inexperienced, should have chosen another route.
Without spoiling to much, let's just say that you will not regret watching this movie even if it feels like. You will laugh, you will wonder why, you will probably cry, not because you are sad but because you want your 100 minutes back but at the same time you don't... And the ending turns into Power Rangers vs Godzilla 😂
