I will keep this short for you.
SAO is an enjoyable anime with a few good fights and some funny moments. There are some downfalls, starting with how in a lot of episodes the protagonist Kirito for some reason seems to have girls falling for him left right and centre and he doesnt really do anything to justify this. He also seems to rocket up the skill level out of the blue and therefore the best player in the game. He works things out while everyone else seems to be picking their nose or scratching their ass.
however it is a fun watch when there isnt any better animes on.
