Yeah, so finished all these books. These could almost be really interesting if they got rid of the whole love story - I know this will cut it from four books to one. For example, the whole werewolf (I'm not going into stuff from the book in case it's a spoiler) plot could have been expanded, and there's certainly a fair bit of back story there.
The vampires themselves (not the boring Cullens) have the potential to be far more interesting, the hints are there in the final book.
Overall, not worth reading unless you got the books for free and have nothing better to do.
