There was a large (but informal) survey done on /r/haskell (one of the largest Haskell communities) last month about "Why Haskell sucks". The results were collated into a presentation linked below. It's a very detailed review that covers just about everything "bad" about Haskell (though I think it views each issue rather optimistically).

EDIT: Also, if you find the colors on the slide show intolerable, the page source is well-formatted and readable. Content starts at line 200.
