What ruined this movie...

What ruined this movie is basically. Shia Leboufs bad acting, and that annoying other kid from school who tags along with Sam...each time their scenes come, I have to skip it.. unfortunately, Shia's in most of it..!
And the badly placed so called humour, but if it was to have been a more serious movie, it would have probably been better.
The story line is ok.. but we should of had more of the Fallen Decepticon instead of just a big Bionicle coming and going for like 5 minutes of screen time.
