It's… good I guess? I mean it's pointless and probably disappointing to some, but I didn't really hate it or even dislike it that much. It simply serves to retell the events of the show and have a nice little adventure at the end, and it does that, so mission accomplished I suppose. It actually cuts out a lot of the boring drama that plagued the show, which is nice. The animation is great, that's one thing that's been consistent throughout this series, which is a plus. If you're too lazy to actually watch the show (and you're honestly not missing that much),then I think you can watch this and get the gist of the show just fine. I had only one problem with this movie. During the scene with that guy trying to get Kirito to tell him what happened in SAO, Kirito says "I need to be somewhere, lets make this quick". It's day out during this. When they're done talking the sun is going down, and Kirito doesn't seem to have a problem with this. Only problem I had.

Majority of this movie was just a recap of the first season and more or less Sugo learning how to swim.

I mean they might as well had only made this an OVA/ a 30 minute episode as I felt that the last 15 minutes in spite of being filled with fan server was the only good part about this movie.

As usual the voice cast including Bryce Papenbrook, Kirk Thornton, Chermai Leigh, Sarah Williams, Christine Marie Cabonos, Jamieson Price, Stephanie Sheh, Erica Lindbeck and Michael McCommine (the main highlight.) all did a good job.

But if you really like the series please do me a favour and skip this and don't waste your 1h40 minutes like I just did.

If you plan on watching the entire series in a single sitting, if I were in your shoes, I'd pass on this, because It isn't needed at all for the future series.

Most of the movie, 85% if not higher, is just a large recap of season 1, with just kirito narrating here and there, meanwhile there are some few new scenes in the present with characters in their non-gaming life talking and having fun.

If you plan on watching season 1, then giving it some time for the next season, then I'd watch this (in other words, watch season one, Wait 2 - 3 months or something, then watch this, to then watch season 2,) just to refresh your memory and get some small added bonus with the new scenes, but otherwise, don't bother.
