If you are a fan on numerous callbacks to famous TV shows, then this one is a joy to watch. Mr. Puzzles was definitely a highlight here for his over the top reactions, well-planned jokes, and the song! Each character has a great role to play here (without spoiling, Bob and Boopkins definitely were the best). Everything in the video flowed so well and was so much fun to watch.
However, I do think it's one of the weaker SMG4 movies for a few reasons. Firstly, some continuity from 2023 was not explained for Puzzles (aside from a few exposition, it didn't touch upon things most of us wanted to know). Also, Mario was pretty much sidelined in this whole movie. While he had the usual funny moments, I found his potential not fully met as he never helped out aside from the third act.
Overall tho, I still really like this movie despite those issues. However, I will say you have to be more forgiving of the lesser known story to fully enjoy it. For what it's worth, I really loved what it did for the style of TV shows and group of characters needed. So I'd say give it a watch for the style alone.
