totally agree.
Actually I think that's probably because ILM didn't have the confidence that they handle the robot action smooth enough.
They never gave you a clear shot like from a distance (except for that Megatron killing Jazz scene).
I got the feeling that they have a problem handle such complex models, gravity wise specifically. If you watch again, there is a shot when Megatron and Prime flew throught that building and fell to the ground, Megatron then picked up Prime and threw him away, that scene look extremely fake, they just seem to have problem handling an object heavy as a truck but complex as prime in action (action I mean they can let him talk, walk even running... no problem, but fighting scene is a lot more complicated actions).
Also the scene when Megatron hit by missiles at the end, that look fake as well. They just have no ideas how Megatron should react to those F22 missiles, they should hire a physics scientist to do the math for them. Seriously this is probably beyond ILM's capability expressing a giant robot (they never gave out the figure how much Megatron weight, and his poiwer, overall the strength of his legs ...) being hit by missiles.
Hope to get some more realistic, more impactful action scene in TF2
In particular, I never enjoy those super closeup shots in those robot action scenes.
