I think so far this is the one of the grossest entries in the franchise. Where some are the good kind of gross, like the omelette that imo is one of the top/most memorable stunts they've done just because it's so awful. But also a lot of cheap gross scene involving basically filming someone defecate, the reactions from the guys is always fun, but most of them felt cheap.
The lost tapes starts out strong with some stuff you'd really expect to have seen much sooner in the series like the tazer and pepper spray. But in general it fizzles out a lot and there's a lot more skits that feel kind of empty, simple or just failed imo. Like the woodchipper was mundane, the devil skit wasn't working, and the ''eddy'' section just failed imo.
There are a lot of small pranks with just the guys and they are fun and keep it well balanced overall. Also gives a bit of a behind the scenes feel to it though really The Lost Tapes is just a 5th season of the TV show. (the 4th season being J:The movie).
That said, must watch for any fan.
