Is Zack and Miri Make a Porno the worst movie Kevin Smith has crapped out (word choice intentional)? Probably not (I skipped Jersey Girl altogether), but his raunchy humor and comic book references aren't as fresh-faced as they used to be back in the dizzying days of early '90s indie film.
Actually, yes - Zack and Miri stands as Smith's weakest film to date, in my opinion. Jersey Girl mostly receives hatred because it didn't cater to Smith's normal audience, but it wound up being a fairly decent and somewhat touching romantic comedy. And it was leaps and bounds better than Zack and Miri.
I have all of Smith's films on DVD, but I have been reluctant to pick this one up....the exclusion of a commentary track also hurts those odds, as I was look forward to one despite the lackluster film.
