I did not, but I did see Inception in the theaters (twice), one time in IMAX, and I know exactly what you mean. But I also saw Ramona and Beezus, Despicable Me, the Guardians of Gahool (sp?) and Toy Story 3 in the theaters last year.
Yes, we have kids.
None of those were particularly worthy of the $50+ we spent on the tickets and snacks each time. Had we been able to download them to our home for $25-35 and watch them there with our own popcorn, I think we would have enjoyed that just as much.
And then maybe I could have seen some of the other big movies in the theaters.
