I gave it an 8, although I could also have given it a 9. It was an imcomparable moviegoing experience to me; I think that if I'd seen Star Wars in its initial theater run, that might've given me the same feeling, the same desire to shout "Gee whiz!" at the screen over and over.
Complaining about the lack of characterization in a movie like this feels like complaining about the lack of ray guns in Garden State. All the same, the movie's sparkling dialog didn't sparkle quite as much as I would've liked, and Polly was far more annoying than necessary, and it wouldn't have totally broken genre conventions if the plot had hung together just a little bit better.
Fix these shortcomings, and I would've given it a 10.
Still and all, this was a flawed masterpiece of a movie IMO. And this Kerry Conran or whoever has a staggering vision, and I'll definitely be watching for his second movie.
