How crap was the expendables?

what a waste of an awesome cast. instead of trying to make it a pure action movie they could have parodied all the casts previous roles and made a right good comedy/action movie. AGREE/DISAGREE? the only part in the entire movie i found entertaining was when bruce willis said (refering to big arnie) "whats his problem" and stallone replys "dunno think he wants to be president or something" lol
