Cheaper by the doszen

I havnt seen cheaper by the doszen yet, but i hear that it is not that good, but can anyone tell what they thought of the movie before i waste my money on going to see the film.
I mean i think Steve Martin is a great actor, he is funny!
I like him in Father of the Bride and Father of the Bride 2, he is funny in them.

So can anyone tell me what they thought of the film.

Thanks, Margy
