Okay, first thing to note going into this is that, well, don't expect the entire thing to be a completely new story. They actually take what I like to call the old Loony Tunes approach and create a story that's basically an excuse to showcase older episodes, though in this case, they all have a particular theme to them, specifically the kids building a friendship with the kindergartners. As such, we're treated to 3 classic episodes, but what makes this film worth it is the addition of a 4th new story, specifically back when Gus was in kindergarten. For the most part, it's fine. I can at least believe most of it, but there is one major plot hole that kind of removes whatever credibility the writers clearly wanted us to think it had. See, it's revealed that Gus actually had the same kindergarten class as the others, and while this is questionable at first, they not only address the obvious plot hole here but also come up with a generally good reason, that being that the others can only remember a fraction of their kindergarten years and thus it makes sense that they wouldn't remember all of this. However, it does not explain why, if Gus had a good enough memory to remember this, he genuinely had no idea who all five were when he first appeared in the series. I wouldn't mind this so much, except this show is actually pretty good when it comes to continuity. They have a nice concept here, with Gus actually being the one who helped all five of the others find their callings, and even the whole subplot with Mikey picking on the other kids was confusing at first but made sense when you found out why he did it. (It also ties into Randal once telling his father that Mikey used to be a schoolyard bully... that's actually kinda neat) Again, I do feel like that one small detail from the first episode kind of contradicts a lot of the forth story, but it's still fine and I like the setup enough that this is more of a nitpick. Again, maybe if the film had been all new material and the main story tying it all together wasn't so paper thin, I'd recommend this more, but if you're a die-hard Recess fan looking for a nostalgia trip, I'd say this is worth seeking out.
