Interesting review, it's good to see MovieBob mixing it up a bit.
The only bit I'd mention that Romcoms or as I call them "Chick Flicks" are a successful and constnatly produced genere because that general characture of "what women want" or what someone's mother is like, tends to hit enough women with a shotgun effect that they come and see this movies, which make enough money, that they continue producing them to make even more money.
Typically, I can deal with a lot of the cliques, except for the bits where people awkwardly but profoundly try and express their feelings for each other. It rarely works, feels natural, or like something anyone would ever say. I find such scenes can cause almost physical pain when I witness them.
I feel such things are best expressed abstractly, a lot of that stuff can be said with a look, and come accross much better in the flow of a movie, than sitting there for ten minutes talking about feelings in a way that makes me want to beat myself unconscious on the row of seats in front of me (or with the nearest blunt object if I'm at home).
I guess girls like that kind of stuff though, since they keep selling it, and a lot of girls seem to think that's the best part of these movies, which is why it kind of qualifies as the chick flick equivilent of a "money scene" that sells the whole thing. An example of the differances between men and women in action.
