As a dramatization of the prologue to Eye of the World, and thus, the whole series, it was okay. The one change they made, with LTT killing himself in a mundane fashion, rather than using the Power to blast himself out of existence might have actually worked better as the kickoff to a TV series, rather than jumping the audience right into the One Power. It might be a little hard to convey entirely through visuals what happened to people who don't know what the One Power is or does. I imagine a substantial portion of the audience might leave that scene thinking "So he turned himself into a mountain?"

The only problems I saw with this were the issues with its existence in the first place.
