Well, TheShape's point was that one character doesn't make the entire film. There are other things there, which he might like if he were to give the film a chance instead of letting one character among dozens of them already ruin it to him.
Yes.
And beyond that, there's the fact that while he might be turned off by the look of the character after seeing the handful of images and 3 seconds of footage we've seen of him thus far, they might actually
like the presentation of the character upon seeing it in context when all of the elements come together (appearance, writing, direction, story, acting) in the film itself. Or, at the very least, it might not be so "awful" to him that it hinders his enjoyment of the film as a whole. It's called being open-minded, or at least, not being close-minded.
If you don't like ANYTHING you've seen thus far, weren't impressed/intrigued by the early teaser trailer, aren't a fan of the actors that have been cast, or simply aren't really interested in the concept of the film, that's a different story. The whole thing just doesn't seem to be your cup of tea, then, so I'd understand not being interested in seeing the film or following it on a forum like this one for the next year.
But if there are one or two visual elements that aren't appealing to you at this point because they don't meet your standards and you boldly state that you've made the decision to not see the film nearly a full year in advance without
at least waiting to see more footage, read even one review, or give the actual film a chance -- a film that might feature fictional characters you like and/or care about -- that's truly a snap judgement and a little absurd to me.
I mean, I was not at all crazy about the appearance of Willem Dafoe's Power Ranger Green Goblin (like many others) as seen in some promotional materials prior to the release of the first Spider-man movie. It's not how I ever pictured the Green Goblin or how I ever wanted him to be visually translated on-screen for the first time. [Side-note: We still haven't seen a visually-faithful Green Goblin on screen.] But I can't imagine making the snap judgement or decision to deprive myself of seeing the film and giving it a chance simply because he didn't look like the Green Goblin to me. There are countless example of people not liking certain things they saw prior to the releases of some big movies, but it's pretty rare to see people definitively state that they wouldn't see those films for that reason -- especially so early on.
Maybe I'm off here, but that's just my two cents. Different strokes for different folks. If he's actually able to hold out on seeing this film in theaters, more power to him.
