After the monumental dissapointment of the last 2 Marvel films: Civil War and AOU. I can't say that I'm too hyped about this film, after watching Civil War I'm not too sure the Russos are the right men for the job here, they excel with more fast paced martial arts type of action and deeper, personal stories. As much as I dislike Whedon I think he has more experience and skill with ensemble casts like the Avengers.
I can't really picture Thanos doing 10 hit combos and triple spinning kicks in the air with the style of action the Russos prefer to emphasize. And then you have the fact that Vision is basically Paul Bettany with face paint, who acts just like Paul Bettany instead of a stoic robot. Not for one second did I believe that Vision was anything other than a dude with freaking red face paint. Yeah Disney you've only made billions on these films, yet still going with the cheap/budget effects I see.
