I guess I'm willing to retroactively paste Ruffalo's face on and incorporate the canon from TIH (and to a certain extent 2003 Hulk), because I think I might have liked it more if it had been him. I just didn't believe Norton as a scientist. Hell, I didn't believe him as not-Edward-Norton, so to me that was like an entire movie about the time that Edward Norton somehow got turned into the Hulk. Honestly, though, disregarding it in favour of a backstory you prefer would be no more than the comics and film writers do every other Tuesday.
