The Great Khali - Not So Great!

I don't understand the point in WWE bringing in The Great Khali. This guy seems to have no skill in wrestling and he isn't even that big! Henry was doing great with a great feud with Taker and WWE just swing him aside and bring in this Great Khali who has no skill. He isn't even as big as he was said to be.

I'm guessing this guy will be fired soon but sometimes I don't understand what the WWE is doing.
