Hello Ghost and The Bros are really fun and enjoyable movies. They similar alike (I don't wanna Spoil it for future watchers tho). Actors in bother were hilarious, the storyline were really heartwarming. So i recommend this movie to future watchers whom have watch either one and would like to watch with the same feels and atmosphere of the other.
