Paul Blart: Mall Cop
"Rubbish, rubbish, rubbish, rubbish, rubbish, rubbish, rubbish, rubbish, rubbish" - Mark Kermode, BBC Radio 5 Live
Kevin James in the first of March 2009's two overweight-man-gets-job-as-security-guard-at-a-shopping-centre comedies, the other being Revenge Of The Sexually Pathological Voyeur. Established itself as a real low watermark for that year (one in which Bride Wars had already happened) - see, for example, the review of Dance Flick:
SIMON: Is it worse than Paul Blart: Mall Cop?
MARK: Paul Blart: Mall Cop is better.
SIMON: But you hated and loathed and detested that with a passion.
MARK: I did. But this is so much worse.
Just to check, Mark took his son (who famously turned to him during Transformers and said, "this isn't rubbish at all daddy") to see it. His son't one-word review was a pained, "daaaaad!"
