I know of lots of people who proclaim that "Linux sux" because it isn't 
Windoze. I can well imagine hords of impatient Java programmers decrying 
Haskell because it isn't Java. ("It's not even OO, man!")

Haskell is many things, but few would seriously claim it to be the 
silver bullet to effortlessly writing bug-free code.

(Indeed, the number of times my Haskell programs have locked up due to 
me accidentally writing let x = foo x...)
