I won't see Tom Cruise films because I think he's a lousy actor. That he's apparently cuckoo is just gravy. A local review called Gibson
"an angry, unstable, self-destructive artist guided by pure instinct." The jist of the review was that it was a response to the prevailing trend in Hollywood to glorify pre-western contact tribal cultures as uniformly civilized cultures that were corrupted by the evil West - but that Gibson didn't necessarily intended the movie that way.
I see about 1 movie a year, and this isn't likely to be it.
