Welcome to the boards, and yes, I certainly hope it is just you!
Lets just wait for 2011 or 2012, we've seen them done to death in comics and cartoons, we need our live action Avengers, the movies are all set within the same universe, the marvel universe, and the movies should all feel like they are part of that same coherent universe..
If you start changing the visual styles between movies... that coherence will be lost, and with the actors they will be getting they don't need to be spending the extra cash on 100% cgi.
