This'll be a short review considering there's not much to say about this, but let me start by saying this is NOT cannon to me. 75% of this "movie" can be boiled down to filler, & fan-service, that had nothing to do with the main plotline. And, when there is "plot" happening, it happens so fast, you almost feel whiplash to how bad the pacing is. I tried to find something to like about it, & the only redeeming qualities is how they still do retain the main ecchi, funny moments from the main series, which was...nice, I guess. Other than that, the ending left me completely & utterly confused, never explained or showed anything I was expecting, just kinda...cuts off. Yeah...uh, not good.
One more note to add, is that the art-style was slightly different compared to any other adaptation (another reason I don't consider this cannon). I don't know what happened, or why they seemed to hire a different studio to make this movie, but it really threw me off & didn't look "correct." At the very least, they could have gotten the original studio to create this adaptation. Huge letdown.
This is the worst anime movie I've seen in years, considering how old this one is though, I doubt many will care to watch it. I only really recommend this to someone who is DYING for more content on this series, but if you're not, please just stay away. It will only frustrate you & leave you scratching your head in confusion over the ending. NOT recommended (& not cannon, if you care).
