I have never got the scientist vibe from his acting once unfortunately. Maybe college professor but not scientist, IMO.
Thinking it over, I like Ruffalo's Hulk better but Norton's Bruce Banner.
Not sure how unpopular this opinion is but I will put it out there anyways. I don't like the over use of callbacks/references in today's movie sequels, some would call it fan service but I can only see it as the studios trying to monetize nostalgia.
