The dreck films far outnumbers the good stuff. I can think of only a few good/enjoyable movies since Iron man 2 came out and not use all the fingers on one hand to count them all. Most summers aren't this vacant.
Robin Hood, A-team, Jonah Hex, Shrek... all very poor movies that don't even compare to a good TV show. It's pretty weak when I can sit down and watch a re-run that is more entertaining than a major motion picture.
By years end, we'd be lucky to have 5-6 movies that would even be considered "Very good." Oh well, it gives me more time to listen to my stereo.
