Well, comparatively speaking, compared to other forms of entertainment a cinema ticket is still a reasonably affordable thing. People aren't even being put off by 3D or IMAX ticket prices if the film is right.
As demonstrated by increasingly high grosses and Hollywood's highest ever grossing year in 2009.
When it comes to quality I expect it's perception but certainly while there are some fantastic lower budget movies out there to be found, your megabudget blockbusters can certainly be as generic as they have always been.
There are always exceptions of course.
