This show had a little bit of everything... action, suspense (in a comic book sorta way), humor, and romance. Terri Hatcher was great in this and Dean Cain made a very down to earth (heehee) Superman. Terri and Dean had great chemistry and their scenes together sizzled with sexual tension. I liked that the show had plenty of humor mixture throughout, with plenty of little jokes about Superman's suit and hair. I thought they did a good job with the progression of the characters and the Lois/Clark relationship. Both Lois and Clark grew through their relationship with one another, becoming better and stronger people.
I have to say that I was disappointed with the last episode. It seemed like the writers just slapped something together to finish off the show, and it really didn't do justice to what was otherwise in excellent series.
