For me, it was worth it to watch the stunts on the big screen with loud Dolby/THX/whatever sound. Especially the views from the air, the jumps, leaps and the on-foot chase through the streets. You can't get that experience from any size TV
Oh, and the Defenders on the big screen are the icing on the cake!
The budget for the movie was relatively high as far as Hollywood goes, but it did not go in to the gadgets. The story line harks back to James Bond's first kills to achieve double-O status. Hence, the lack of gadgets. Although, that Aston-Martin would be enough of a gadgetfor me.
