Marvel Studios interfered with the production of the second Avengers movie so many times that Joss Whedon is now doing emergency surgery on DC's Justice League movie and developing a DC Batgirl movie. Yay!
Avengers: Age of Ultron is a busy, crowded mess with plot holes one could fly the SHIELD helicarrier through. It's a good time-waster on TV because one can pause it every 45 minutes or so and because, as with the majority of Marvel Studios movies, it looks like the world's most expensive movie to have ever been shot on the same videotape used for 1970's Doctor Who episodes. Jesus, I hate the colour palette of most Marvel Studios movies. Lightly recommended.
