Being trapped inside a game probably has its ups and downs but this anime makes it look awesome, well not for the characters.
I liked the story and it was really enjoyable, I liked the way the villain was the creator of the game, and then he's been with them all along. That was cool and unexpected. I hated the second villain but villain-wise he was decent and is one of those you have to hate. The story was really really good and easy to enjoy.
The art was amazing. I loved how the characters looked. Their eyes looked amazing and I liked the hairstyles. I loved how Yui looked, Yui was so cute and she always looked happy. Asuna was also done really well. The background looked really nice especially in the end of the first arc.
The sound was good. I liked the background music for most scenes. I liked most of the voices, there was one or two that I didn't like. I liked the opening themes too.
The characters were amazing. I loved how the second villain was just pure evil and you have to hate him and his voice sounded incredible (I'm so not saying that because he's voiced by my favourite voice actor) The other characters like Kirito, Asuna and Yui were also really good. I don't like Kirito's cousin Suguha though. She really annoyed me. YOU CANNOT DATE YOUR COUSIN!!!
Klein was also really funny and I wish he was in it a bit more. Yui and Asuna are my favourite characters in this anime. I just love them both.
Overall Sword Art Online is really enjoyable and I highly recommend it
