So what's the deal on "Mall Cop?" Is it any good or is it all hype?

I don't want to waste good money on a bad movie. Who has seen it?

1. I saw it. Define 'good'?

It's okay. If you're not expecting anything more than a dumb, silly movie that's still kind of fun, you won't be disappointed.
Just don't expect anything more than that.

2. Rotten Tomatoes gives it 27% favorable. Better than "Bride Wars" worse than "Hotel for Dogs"

Consensus: Paul Blart: Mall Cop has some laughs, but its plot is flimsy and lacking in any sustained comic momentum.

I haven't seen it, but if I did, I'd have VERY low expectations.

3. Any movie with the line "Who is this guy?" in the trailer is by law going to be stupid

But some can be fun and stupid.
