To me Dean Cain will forever and always be Superman. I'm partially biased as he was the first Superman i ever saw fly through the skies. I remember coming home from church on Sunday nights and watching Lois and Clark with my dad. It was the one thing I looked forward to during the week. I would grab my Kenner Superman figure and sit as I watched Clark get closer to Lois, a new villain of the week that would take on the Man of Steel and of course Perry giving out advice with stories of Elvis tied in. To me the show was all about character. It developed the characters of Superman better than any other live action showing of Superman in my opinion. Which on a side note, the comics could learn a thing or two from this show on that issue, but I'll save tha rant for another time.
I respect what Christopher Reeve did for the character and to a generation, he is their Superman. Just as Tom Welling and George Reeves is for their generations. But I will watch this series till the day I die as Dean is my Superman. Now I'll admit it wasn't perfect (Lois getting amnesia, the clone ect.) but same things were in my book (the characterization of Clark, the Kents p, Lois, Lex the New Krypton saga and of course Tempus, duh). But in the I can sum up the series with this quote from Clark, "Clark is who I am, Superman is what I can do." And it was that philosophy that made Dean and the show special to a lot of fans.
