Great supporting cast in a movie that is just not ever funny.
I think this was an effort to revisit the sort of sex-romp comedies of the 60s that were also rarely any good. The closest comparison I can think of is Barbarella, but that had a lot more sex in it.
It reminded me of dimestore spoof books like Bored of the Rings and like that. Tries so hard to be funny by being crude and never is.
Setting aside the comedy it wasn't a bad fantasy film. The effects were pretty good and it had some nice visuals.
On the whole I'd rate it 4/10. Not as bad as it might have been, but even a single laugh would have been nice in a 'comedy'.
