I found it to just be okay. But my main concern was the use of "magic" on the show. There was no umph to what John was doing, he just mubled some words and it just seemed to work. I'm hoping they do a better job once the series get going but that's one of ny big concerns.
Also the tag at the end was just crappy. The effects were poor, the voice over was just not that great and the scene itself was kind of confusing (we're they just thugs or what and why was John there).
