While I agree with you about this particular fight scene, I think it is somewhat symptomatic of an overall trend of lazy action movies. It seems to me that these days the final battle of every action movie, just comes down to filling the screen with as much CGI and explosions as possible, and the hero just shouting loudly and heroically and vanquishing his foe with sheer hero power, there is no clever battle of wits anymore the hero doesn't concoct some clever scheme to beat the bad guy they just win because they have too. The problem is I can't think of a an action film in recent times that breaks this mold, even good films like J.J Abrahms Star Trek end with a emotional fist fight and yet more explosions.
Funny thing, as much as I love the final confrontation between Optimus and Megatron in the original animated film (and it is my favourite TF fight scene), I do think the part where Prime throws Megatron is flawed for the above reason. One moment he's like "I'll rip out your optics" and struggling with Prime, the next minute Optimu's just causally pushes Meg's arm away, who proceeds to go all limp and just LETS Prime hurl him into the pavement. It just doesn't match the intensity of the rest of the fight and is the only real flaw in an awesomely constructed fight scene, but it bugs me every time I see it now!
