That's the way I felt about it when Glee covered Journey, BUT I think by the time I saw Rock of Ages, while I felt like it was awful the first time, it kind of grew on me when my mom wanted to watch it again a few times.
At least I liked the "hit me with your best shot" segment with Zeta-Jones, and Mary J. Blige had a soulful voice as opposed to the generically Glee-like vocals of the rest of the cast. I think it had enough people I like and thought were funny, and reminded me of enough 80s songs I could look up outside the movie, I stopped hating it so much.
Still, we're not on entirely different wavelengths on this; that Glee chorus cover of "Don't Stop Believin'" is a crime against humanity. I liked Blige's take on "Anyway You Want It" though. Might have been the stripper acrobats that sold that one though, not sure..
