At this point in the summer, even in the years listed, nothing happens. The top two earners of the year, both of the Marvel flicks, were summer releases.
Not coincidentally, they were both good movies. Nothing else looked even remotely interesting (though Liam Neeson’s latest Taken-style film might be decent).
It was a pathetic movie release cycle for the summer.... PIXAR film got delayed, so there was a huge hole in the summer family film offerings.
