Just saw Dark Shadows last night, and I really enjoyed it. Girlfriend didn't as much. It didn't really get to The Brady Bunch Movie levels of affectionate parody, but, especially by the third act, it certainly did feel like it was milking as many old soap opera cliches as it could.
"You weren't fixing my blood. You were taking it for yourself!" *dun dun dun*
"I was actually a werewolf all along!" *organ chord*
"I was the one who made you a werewolf!" *higher organ chord*
And even aside from that, the dialogue was pretty sharp, the porcelain body effects were quite imaginative, and most of the jokes worked.
A few things fell flat, like the character of Roger, whose "I'm an unscrupulous deadbeat dad" subplot came out of nowhere and was resolved immediately, as if the actor just wasn't available to be in the film's climax. And I couldn't help thinking that, with the power to control people's minds like Barnabus has, several problems could have been tied up a lot more easily. Many of the characters didn't feel like they had enough of a chance to develop, or even get screentime, in lieu of Depp. Also, Christopher Lee's cameo was rather wasted.
All in all, though, I found it extremely enjoyable and wouldn't mind seeing it again.
