Ehhhh, not bad but not great either.
Here's what I liked:
-The backgrounds were awesome. They looked very anime-fitting. Kudos.
-The animation was pretty smooth.
-The audio wasn't bad quality (the acting and writing is another matter).
-Naruto being painfully obviously crazy stupid gay in love with Sasuke is accurate.
Here's what I didn't:
-Doing a bunch of ever-changing weird faces is incredibly overdone now and hasn't been funny since Ren and Stimpy went off the air. This is no exception. It was just annoying and distracting and frankly still images would have been more enjoyable to watch. It's a desperate plea for someone to find your art funny, like the visual equivalent of when you and your friends are singing a song that you know they might make fun of you for liking so you sing it really poorly and offkey and make up random lyrics about how much the song sucks and stuff... Oh wait...
-You sung a song really poorly and offkey and made up random lyrics about how much the song sucks and stuff, again a desperate plea to fit in and be accepted. It's one thing to try to make up some witty parody lines that poke fun at it, but you didn't try to do anything funny with the song (at least I hope that wasn't your idea of witty humor) and it wasn't really necessary to include the song at all, so basically what you did could have just as easily been achieved by ending with a big message that said "Naruto is for nerds. It's okay to like me because I don't really like Naruto. It's poopy. Am I popular yet?" Basically the same as when someone with no animation skill who's never felt the need to make a cartoon decides to make a really crappy cartoon of Justin Bieber eating dog poop. It's not inspiration or some profound statement or even practice for something better, they just want to be popular for hating something that it's okay to hate.
-Between the endless dicks, the faggot comments, and the out-of-character affection Sasuke showed it seems like you really just want to draw boy love yaoi stuff but, as this flash illustrated, you're not willing to admit to liking anything that your friends won't approve of. Don't worry, I can read between the lines. I studied psychology. if you keep repressing those emotions you're going to to rape your grandfather so just let it out.
-Overall this flash didn't rely on wit or anything, just a hope that weird drawings of faces and a few sudden random mood swings would come off as funny. Unfortunately it really just didn't.
