Coming from someone who thinks the 1998 film is bad I liked the TV series. In fact I liked it so much I wish that more people would remember that one instead of the movie. They were able to capture what made the Japanese film fun and exciting. I also like what they did with Zilla, like his Japanese counterpart they made him smarter, in some of the fights he was in you could sort of see how he was trying to work things out in his head to overcome the other monsters. He even showed restraint. He was an actual character in his own right.
I also like the redesign they did for the show, they made him look more like his Japanese counterpart which is a plus in my book by changing the shape of the head and the body slightly. He looks less like a T-rex on steroid and more like a... Godzilla.
I hated the movie, but the tv show was surprisingly good. Which just goes to show if you have some people who know what they're doing and actually gives a damn, you can make almost any premise good.
