While this pilot didn't show a fantastic amount of originality in its approach, it enchanted me for its full hour-and-a-half. There were lots of nice characters that shouted development and history so that was really easy to get into fast. The addition of the child, Maya, looks to me a real gem too. She could be the bringer of some of the best mystery and suspense elements to this show.
I'll definitely continue watching The 4400. I'm always in for some long and plotty show with interesting people and actions and this seems a definite example of that category. A nice start, though the two "leads", Diana and Tom, weren't sparkling enough to my taste. A lot of the dialogue and acting between them needs fine-tuning but I'm pretty sure that it'll all work out. Considering this show ran for 4 seasons, they had a lot of time to work out the flaws and smoothen up the formula. Can't wait to watch the rest!
