If this were on its own and had a different name, I'd recommend this show and get right behind it right away. Don't get me wrong, the writing is good, and most of the cast, Townshand included, can act, but the problem lies within its name.
I have no idea what possessed these people to give it the Night Stalker license. Its intriguing, its entertaining, but it sure as hell isn't Night Stalker.
The first problem is that this isn't the Karl I know. McGavin did a great job with the character and his attitude and wit made the original show the hit it is today.
Townshand meanwhile doesn't just have that magic. I'm well aware that nobody, and I mean nobody, can be as good as the original, but if you're gonna use the license, use it right and give him at least some of what made Koltchak Koltchak.
The second problem is that this is set in LA. The original was set in Chicago and that's fine, but the new one just becomes "Yet another supernatural tale set in LA." If it were set in any other city, maybe it'd have more merit.
Also, this just doesn't feel like Night Stalker. It's supernatural and the first ep was thrilling, but this just doesn't feel like the original.
So while this show is good, its not Night Stalker and it would have been better if it were something else.
