Unequivocally, yes, it is way better than the theater. I have a 134" curved 2.35:1 screen with an Optoma HD3300 and 3D movies are just ridiculously awesome with a DLP projector. When a well done 3D flick gets thrown in (Transformers 3) I'm grinning from ear to ear. Don't get me wrong, I love 2D and it is something of an event to watch 3D, but it adds a whole new level of immersion that is well worth the price of admission. I did just purchase some QS8's for surrounds and was laughing when my friend told me that the sound was 3D. And he was sitting way out of the sweet spot (behind the speakers at the bar table). Love the QS8's.
