A few thoughts: I'm not a huge fan of Bruce Campbell, but I enjoy him enough. He's the kind of actor who's able to sustain a marginal script, but you have to enjoy his exaggerated acting and swaggerific personality. His best performances are usually just extensions of himself, so it makes sense for this shamelessly self-promoting and satirical autobiography to not only be directed by Campbell himself, but featuring Campbell playing himself as well. But don't be mistaken, this isn't an autobiography in the traditional sense, but rather a cheesy action horror fantasy about the aging actor being enlisted to help fight an ancient Chinese ghost. It's pretty dumb and you can definitely tell the script was trying to pull off Bubba Ho-Tep, but sadly lacking the humor and charm. Many of the jokes here fall flat, are incredibly predictable, and never really build up into anything. It's just lousy one-liners, one after the other. Ted Raimi is in it, too, in case I haven't made it sound unappealing enough already. I enjoyed bits of it, but it was lazy and too meta for its own good.
Who would I recommend it to? Super fans of Campbell who somehow haven't already seen this movie. Otherwise, you must shut off your brain to enjoy it.
