Along with an avatar... you also need some help...
I saw this last week, and it was totally awesome. I liked it best when they were at helms deep, and gandalf and the rest of the rohan came over the hill and started beating the crap out of the uraki-hai.... gandalf beating them with his staff, it was awesome. I think they had too many jokes about gimli though, with him on a horse and behind the wall..... but, i give it a thumbup: as jared tried to do!
