Guardians of the Galaxy was a big, fun and enjoyable hit. Not big enough to save the box office.
America went from one or two “blockbusters” a year back in the 70’s, to four and five “Tentpoles” a Summer now in the last few years. Americans are, I think burned out on ‘event movies’ and they are not going to plunk down 20 bucks to see a flick when they can own it in a few months for the same price.
Unless there is a flick that absolutely needs to be seen on a giant screen (like Star Wars) there’s no reason to go pay and see it in a theater.
Plus, there is a lot of crap out there. Hollywood is out of ideas which is why it is resorting to going back and hunting through comic books to find something ‘original’.
There are now dozens of television drama series that are far, far superior to the crap that the film industry puts out
You can DVR them and watch at your convenience.
