Saying Firefly sucks might get your killed in the circle of friends I roll with.
Seriously thou, I never understood why people claim Star Wars is Western. Maybe for like 5% of it but that's it.
I liked Dollhouse but I definitely didn't love it the way I did Firefly. The story and characters weren't nearly as compelling.
As for 3D movies in the theater Avatar is still by far the best (technically) one I've seen. I'm going to put Transformers3 in a tie with Avengers for second place. Everything else I've seen doesn't even really deserve to be ranked. I've seen nearly every 3D movie in a converted IMAX theater for comparison.
