Sword Art Online: Extra Edition

What a masterpiece. As expected of the legendary SAO series, one of the greatest animes of all time. Where other series would make a boring clip show of scenes from the previous season as a lazy cash grab, A-1 Pictures in a brilliant move makes a recap film that is enticing and able to captivate the audience. The shock as i saw many low ratings only lasted a short while, as I remembered the complexity of SAOs brilliance that makes it hard for the average anime watcher to understand and simply fly over their head. A must watch for all SAO fans or people with ... a high enough intelligence to comprehend its glory.

Also nice tits.

Sword art Online: Extra edition is a combination of an 80 minute summary of the first season and a twenty minute episode that is chronologically after the first season.

The story of the summary is the first season told as recollections by various characters and is okay as far as summaries go. One of the recollections is by Kirito who is talking to Seijirou Kikuoka, the member of the ministry of Internal Affairs and Communications, who appears in the second season for the first time. This meeting is referenced in the second season but isn't important and you don't have to watch the summary for ... this part.
The summary goes over into the 20 minute episode quite seemlessly. The episode itself is all new content and is about a quest in Alfheim Online. Overall this episode is fun to watch but has no relevance to the overall plot of the anime.

The characters, voice acting/music and animation are all the same as in the first season.

Overall whether this special is worth watching depends on what you want to see. If you remember the first season well then the first 80 minutes aren't worth watching. If you simply want more SAO content then the last 20 minutes can be fun to watch.

If I wanted to be reminded of the story of the first season, I'd read the f*cking wiki. Absolute waste of time, don't even bother with this one. The story is awful, art/sound is on par with the first season and I was bored watching what was essentially deja vu for an hour and a half, since the vast majority is "el very stern government man" having Kirito retell the events of the first season (in great detail, mind you) for literally no reason but to fill content for an hour and a half so they can print money out of something that is essentially ... a watchmojo top 10 on "epic things kirito did in SAO season 1".

Oh wait, did I forget that the other portions of this movie are just the girls swimming in the swimming pool that is EVER SO CONVINIENTLY behind this innocuous building. Do you like tits? This movie has plenty of them.
