Back from the Perth midnight screening.
Eh. It had all the same faults as the second except the writing was decent this time around.
I actually liked the Wreckers - the United Kingdom accents suited them (esp. Roadbuster). I felt finally the right balance between human and robot dialogue was achieved, although was a bit let down that Shockwave, Soundwave and Dino didn't get more (or any in Shockwave's case) lines.
Was quite disappointed with the role of Shockwave - I spent the entire time waiting for him to bust out some line about logic but was let down when he was offed without making anything but grunting noises.
I didn't quite follow the ending - it was/is 3am but why did Prime randomly off Megatron? This caught me slightly off guard as in all the adaptations he made peace after finishing Sentinel Prime, whereas in the movie he basically randomly killed him after Megatron helped him.
As I said, basically RotF with competent writing. It still had the same problem of the end set piece going for so long that by the time it ended I really didn't care why it began. It also felt overly long. I'll probably see it again at some point but I'm not really in any rush because it more or less went for three hours, and don't feel it's worth that kind of time a few days after seeing it.
