I normally love Steven King novels and the movies made from his works are decent. But the other King fan and myself got bored with this mini-series.
It almost looked like they did not have enough money to do things right. Empty streets/sets were common, odd-events thrown in without context to the rest of the story, some odd characters appearing without reason, etc.
Check your local rental store and rent a disk or two before you buy.
If you've read my review already then skip this post.
I HATED this when I watched the pilot on TV. HATED IT! I wanted this show to fail in so many ways, but watching it on DVD was a different story. I got sucked into the show and I couldn't stop watching. I thought Columbia TriStar did a very good job with the set, and while it's not for everyone I think it's worth a rental if you're interested in Stephen King's material.
On TV, a few episodes were good but most felt like filler. The finale explains everything, and is good, but I don't think it pays off on the time investment. I don't care what King says, a LOT of the mid-run episodes are simply pointless.
