I checked out this movie from the library so it might have been around for a while. I started watching it late last night and didn't stay up long enough to see the ending. I'll see the ending tonight.
I like what I've seen so far, it's amazingly clean.
Andrew Garfield becomes spider-man through a process of cross-species genetics. And a scientist becomes lizard-like because he wants to grow back his missing arm. Coincidentally, The Daily Sun had an article on July 10, 2013, about the Mayo Clinic: "Researchers on brink of regenerative organs"
Like the movie, the Mayo Clinic is probably keeping its work on cross-species genetics a secret.
