I liked it too. A lot of respect was paid to the original series. Lou Ferrigno was in it, they showed a clip from "The Courtship of Eddie's Father" (starring Bill Bixby), the whole gamma gun aiming on his forehead, and the piano music from the original series.
There was also quite a bit of humor, those who haven't seen it, get ready for a laugh after the taxi cab ride.
Liv Tyler looks good, almost as good as she did as Arwen.
