I would get mad and actually walk out if it turned into a porno film. Whether you like that genre of film or not, it does not belong in Star Wars. I'd probably sit there shocked at first, and if it kept going I'd definitely be disappointed that Lucas turned into a perve and I'd walk out. However, there are many things that would disappoint me and/or make me not like the film, but not necessarily make me walk out: 1) Various characters of Sesame Street, Fragile Rock or The Muppet Show making cameos and/or having a prominent role in the film. 2) Turning it into a musical. 3) Yoda farting. 4) Anakin and Obi-Wan busting out into a tap dance routine during the duel. Eh, you get the picture. Anything that doesn't fit, basically.
