I watched a movie really late one night several years ago. I believe it had a very low budget, but the actors and production team did a great job with the film regardless. The only part that my brain can recall right now. Very gorey, very bright colors. The main thing I remember is the group getting together in the end and making improvised weapons and then fighting the bad guy/monster. I know this one is gonna be tough, but any help would be greatly appreciated.
