It's a pity; I enjoyed the first Bridget Jones. It was likable. But it was based (loosely) on Jane Austen's Pride & Prejudice. I haven't seen the second one, but it sounds like I Love Lucy as directed by Woody Allen.
... of course, it IS a little ironic to launch a diatribe against Hollywood for judging women by their looks and then adding that Bridget's hair looks like crap and she needs an Extreme Makeover...
