I thought it was a decent attempt. Special effects arent on par with the likes of Jurassic Park, but this is a TV series and probably would have much to spend. The story line is good, and doesnt appear to be as cheesy as Torchwood/DrWho!
After seeing the trailers for it I thought it was going to be a poor attempt at a Doctor Who but I thought it was pretty good. Even better for her being in it
