Transformers 3

Just watched the Transformers 3 (Transformers: Dark of the Moon)trailer. As usual, the cinematography is just gorgeous. I am amazed by the effects in those movies.
I am not a huge fan of the Transformers movies, though I was a huge fan of the cartoon and thought the toys were really cool.



I can't say what it is exactly that I don't love about the movies. They have some great qualities

• Great director
• Good acting
• Spielberg
• Amazing effects
• Big budget
• Humor
• Ensemble Cast

All of these things are things I would typically say add up to a great movie. Maybe it's the stories? Maybe the cram too much into each film. I like parts of the movies, but I always find myself sort of hoping for the end of the movie to come along and then feeling like it is a long way off...and I typically like long movies (love the LOTR trilogy).
I can't say what about Transformers doesn't appeal to me. Don't get me wrong, I will see it, in 3D, but I get the sense I should like these movies more than I do.
Can anyone share their thoughts on what they find appealing? Maybe it's contagious.
