This is pretty much the exact piece of poop that you thought it would be from the commercial. They mixed in a knockoff action scene from 300, a knockoff arena scene from Gladiator and a big knockoff speech from Braveheart together and put it through the 3D machine so that they can get extra money out of it and released it in the beginning of January where nothing good ever gets released.
I wouldn't recommend anyone wasting their time or money on this. It's a joke that this was even released in theaters and criminal for anyone to pay in the ballpark of $15 to watch it.
