Of course you can have an opinion RT. No problems with that. You just have to excuse us die hard fans who find it very hard to agree with you. Believe me when I say that we're not ****ting on your opinion, just disagreeing with you.
As for the opinion itself, I can't totally disagree with you. Some of the acting does seem campy (or whatever) but, you have to realize that seeing this stuff in a trailer, without the context of the full scene is hard to really judge. It's just quick clips of dialogue, ya know? Besides, sometimes for these trailers, original dialogue recorded on the day of shooting is used. Most times these things are fixed or improved with looping.
I guess what I'm trying to say is... just wait and see.
Welcome to the GR Hype, by the way!
