what happen to all the summer box office films?

yeah Iron Man with Robert Downey did huge business and Probably the standard film for the late spring/early summer then you got the hype for harrison ford and Indiana Jones, then you have Sex in the city with Sarah Jessica Parker and Company and then lastly Will Smith's "hancock. but on a whole where is that Summer surprise or those left and right monster films at? also the local theaters ain't playing if your film is going Wood then they are gonna Pull it. Summer has always been the time of the year to venture off to the movie theater and spend money,etc.... nowadays rentals from Net flex,blockbuster,etc... are doing business and getting the films fairly quickly. the movies need to step up there game basically to draw some real interest again to me.summer is half way over and only a handful of films have lived up to the hype.
