As many others have pointed out, condensing 22 hours total of anime episodes into a two hour long film is impossible, full stop. I, however, don't think that's what they're really aiming to do with this, since it IS a recap, after all. It highlights the most important moments that, if you have forgotten some, you can catch up on in merely two hours. Which is fine. Definitely. Absolutely not. It highlighted things, yes, but it all went by so fast that if you blinked you could've easily missed a key point. Good thing you can rewind, huh? Yeah, well, that still won't fill in the gaps. There are so many holes in this thing they should slap a "Swiss cheese" label on it.
It all depends on what mindset one goes into this film with, really. At first I admit I was expecting something else, but after finishing it and readjusting my perspective, it's not all that bad. Except, again, they DID try to cram the story of 22 hours into a measly two, which means things in this film happen so fast you barely get a grasp of what's actually happened whether you forgot or not. If you did, I'd argue that's even worse, because that just means you still have to go back and re-watch parts of the series because this film doesn't delve into detail, at all. Because there's no time for that, or it would've been a lot longer.
... In conclusion, these recap films become more and more difficult to watch because a lot more has happened since the last one. And they always have to start from the very beginning, then compiling everything that's happened since. Which is a weird and honestly terrible idea. If you wanted a summary at this point without having watched a single episode until now... I'd still tell you to watch it all from episode one. Don't waste your time with these films. Don't.
