Yup. I saw it once and couldn't tell you any character's name besides Jake Sully and that is only because Hot Toys made him. I wouldn't have remembered that otherwise. That movie. It's probably the lowest ranked movie I've ever sat completely through. I just hated everything about it. The characters. The story. The preachiness. I didn't see it in 3D but as said above, if it needs a gimmick to work, it's not a great movie.
TFA in my opinion was a fun, entertaining movie. I don't love it. I don't hate it. I don't think I'll be watching it anytime soon if ever again. That said.... I want it to knock Titanic and Avatar off their thrones because STAR WARS.
Does it help I don't watch my antenna and don't have cable/dish? I don't see constant ads for TFA outside of YouTube. I saw a lot of crap in the store but that happened with TPM, RotS, and I've heard RotJ back in the '80s. It's nothing new. I just ignore it all. Whatever. I agree it's annoying but I don't have to endure the Star Wars overload. I've learned to ignore it and embrace the parts of the franchise I love (the Original Trilogy, the Expanded Universe, and for too long of a time the Hasbro action figures).
