I am with you on the things like the sonic cannons... We want to push the envelope of depicting what makes the sci-fi/fantasy world of comic books so great.
But (for now at least) I really think that there is a line that we should approach with some trepidation (a line which I believe is gradually sliding away). As more films get made, and more suspension of disbelief becomes acceptable by the general movie-going audience... then we can delve deeper into the Marvel mythology.
But then again, you only said:
so I am just grinding on for no good reason I suppose.
