1. The show is a huge slap in the face to the fans.
2. The characters are so nasty and rude to each other. Alvin is a heartless jerk, Simon is very irraiting, Theodore is a spoiled brat who doesn't have a mind of his own, The chippettes are bullies, and Dave is a abusive jerk. It doesnt help when you have annoying characters like Ms. Smith, Cheesy, Officer Dangus.
3. Every episode makes you want to punch the screen. It either gets really annoying or Alvin just ruins the episode
4. The way the use the famous "ALVINNN" in every episode gets very old and annoying
