Many people don't like his dad and make baseless assumptions that he's an RPO quarterback. As you say, it's all about where he lands. If his last name were Manning, there would be no complaints.
I agree with that. Statistically, he did really well and improved every year. He doesn't turn the ball over alot and completes alot of his passes. It tells me that he also makes good decisions and must be pretty good at reading defenses.
As far as his pops is concerned, I never understood the hate he gets either. Attention seeking they say, but this is Primetime! What else do you expect? He talked the talk and he walked it. Multiple super bowl rings, HOF player and many consider him the best to ever play his position.
