Did anybody try EXPLODING that stone?

The official trailer is out for Guy Ritchie's King Arthur: Legend of the Sword, which looks cheesy as hell. (The official plot summary describes it as an "iconoclastic take" on Arthurian legends, which apparently translates to "now with loads more explosions".) On the other hand, I found Ritchie's remake of The Man from U.N.C.L.E. unexpectedly awesome, so I'm trying to keep an open mind.
