Not really. I like Avril and I like this song. I just remember her bitching about wanting to do deep, dark music and 'What The Hell' being so impersonal to her, that it's hard for me to think this is the music she wants to be making. But this is better than the music she wants to be making so I'm not mad.
It's cute and I could see it possibly doing well on radio, but the lyrics and the song as a whole just scream "cheesy" to me and I have a hard time enjoying it.
