I think the film does a great job of giving you an experience similar to what you get from the comic.
As an old guy, I was pleased to recognize the characters Mick Jagger, Truman Capote, Andy Warhol, Pat Buchanan, and others. I did miss "Dick Cavett," and I also didn't notice Janis Joplin singing "Me and Bobby McGee" in the background -- but both were listed in the credits.
Ozzy's endgame scheme in the movie makes at least as much sense as the comic's version -- although we DID get a SQUID, if you noticed.
Anyway, this was just a chance to share my latest piece of suggested merchandising: The Smiley WatchTie.
What do you think?
