It's extremely hard to make a decent blockbuster – what with all the fingers in the pot – but when it happens it really pays off. Master & Commander, the Spider-Man movies and Scorsese's own Gangs Of New York are recent examples. The Aviator comes fairly close, but comes off a little disjointed as it rushes from one scene to the next.
Side note: I actually sought out theater management to fix the projector's colour problems early on in the movie. Anything green was showing up as a bluish gray, most notably a sequence on a golf course. The next night on the Oscars the same sequence was shown – bluish gray. Turns out it was an intended effect meant to look like an old-timey colour print. I felt like a total heel.
Theater idiots: A few old ladies beaked at how loud the trailers were.
