@wannin: I don't hate the romance genre per se, but I hate the majority of movies that aim to be "romantic comedies". My reason for this is that try to be two things at once and more often than not fail miserably at being either.
For purely romantic movies ... I don't see a whole lot of quality there. There's only so many times you can tell the "boy/girl likes other boy/girl but:
1)The relationship is impossible for some reason(all options below are options of this)
2)He/she is not in his/her league
3)The love is unrequited
4)He/she is already in love with some douche/slut which treats them poorly but they can't let go for some reason
5)The parents of both won't let it happen
6)The friends of both think it's a terrible idea and will never work, and that it could only bring suffering/tragedy/dead ponies and such
n)etc,etc ...
Then there's the predictability of the entire plot, the fact that non-happy endings do not exist in the genre, and the general assurance that love is the most powerful/awesome thing ever and nobody stands a chance against it, which is completely divorced from reality. I just don't feel as if it takes a whole lot of skill to pull off a romantic movie, but maybe that's just me. Often part of the message is that nobody has, is or ever will be happy unless he/she is in a romantic relationship, which is laughable, at least to me. I've been single(by choice) for my entire life and I enjoy my lack of chains immensely
About Transformers .... eh, Michael Bay. Explosions. Wow, we haven't seen that before. Good effects, decent performances by the actors, poorly executed story. Not among my favorite movies. When I was a kid there was a Transformers Beast Wars 3d animated show on TV. Now that was awesome, especially for that time
