I broke down a few weeks ago and watched Twilight and New Moon. Enjoyed them so much I read the books. I am currently reading Eclipse and went to view the movie on Sunday, July 4th. I thought it was great. I laughed out loud at parts. I got anxious at the love parts. I liked they way the worked the engagement part and finally introduced some "real" teenage hormone items.
For being part of a series, its was enjoyable, entertaining and worth the price of a ticket. It is not Oscar material, but for entertainment, as what most movies are for, it was definately a winner. I recommend it.
