I've been anxious to see this for a while now, because the trailers intrigued me and I felt this would be one of those non-typical romantic comedies, which of course are the only kind that are really good. I was only partly right, but not in a bad way.
Let me see if I can explain.

He's Just Not That Into YouI absolutely loved this movie, and I'll tell you why. Two things. One, as I had hoped, it's not a typical romantic comedy. You can't guess what's going to happen by just looking at the poster or watching the trailers, and I love that about it. Two ... well, it
is a typical romantic comedy. In that it's essentially still a slave to the rules that make
good romantic movies satisfying. Sure, the complications are there and make it interesting and genuinely (as opposed to eye-rollingly) suspenseful. But you want to leave the movie knowing that the characters are happy, or at least okay.
Let me put it this way, for you fandom types: If you like "shipping" in your stories, beyond the most simplistic definition of that term (meaning you like a little meat on the slash, as it were, along with maybe a little gristle), you will enjoy this movie.
( Get yourself some ribs and some ice cream, because you have been dumped. )
