Reading through these comments on Touching Evil I have come to the conclusion that if you were expecting the show to be a carbon copy of the British original, you were sorely disappointed. HOWEVER, if you allowed the show to be it's own entity, you were instantly struck by how different from your average US TV drama it actually is.
First of all, the principal actor, Jeffrey Donovan, is no Robson Green (from the original BBC series). He is, however, a phenomenal Method actor in his own right and should be congratulated at nailing such a complex character so perfectly. Secondly, it should also be said that the persons responsible for all the negative commentary on this particular thread have never commented on the obvious quality and chemistry of the other cast members: an amazingly important thing in ANY show. And thirdly, none of the detractors have said that they bothered to see any other episodes besides the pilot. Pilots, as a rule, are always the roughest draft of any television program and should therefore be given the greatest leeway.
For those of you who are true fans, there is a website petition for giving this show a second season:

In summation, PLEASE have no preconceived notions that this is going to be the same as the BBC original. If you're that into the British version, I'm sure you can find the three episodes that were aired somewhere online on DVD.
