A friend lent me a copy of "Horrible Bosses". I managed to get through half of it...then ejected the CD from the machine in disgust and did something else instead. I'd call it a "bad film", you betcha!

Why? Well, it had a dreadful script. Awful dialogue. Very exaggerated characters whom I could not believe in as real people.

Is that enough to qualify as "bad"?

I find these same problems with a great many films these days...the dialogue isn't like that of real people...it's a sort of alternate-reality Bla-bla that sounds "cool" and "funny" to the people who write it because it sets up tension between extreme opposites who are gross stereotypes of some kind, but it's quite unlike most people in real life. I call that very bad scriptwriting. Horrible Bosses is a horrible movie. If I'd acted in it, I wouldn't want anyone to know! ;-) And I'd walk out of the theatre wearing a bag over my head if I'd had the bad judgement to PAY to see it. Fortunately, that didn't happen.
