yeah, it's one of those things in the movie i didn't like. why didnt Starscream just boosted and fly up high as far away as he can taking Sam with him. or even before that, why didn't Starscream just sprayed the place with bullets and rockets to make sure Sam is taken out. i dont remember exactly now if whether Starscream got snagged around some cables which prevented him from just flying away after his one eye got taken out. but he just went like "ow ow my eye my eye!" i have to see that scene again to check if it made any sense.

 

I didn't like how Megatron attacked sentinel prime. He made it too easy for optimus to finish him off.
