I’m one of the few people who were curious to see where Warner Brothers might take the “Clash of the Titans” franchise. The 2010 remake didn’t exactly give us reason to anticipate a sequel (my bottomline for that movie was “mythologically mediocre”), but I still have great affection for Ray Harryhausen’s 1981 stop motion movie of that title, and Greek Mythology offers endless story possibilities. So I was somewhat hopeful that “Wrath of the Titans,” the sequel that opened last week, would improve on “Clash.”
