I grant you that the History Channel does show some non historical movies, but overall it is one of my favourite specialty channels. Over the weekend the had a WWI weekend of programming, which I thought was very good - both documentaries and movies.
The channel that I am most disappointed in is the Scream network. When I heard there was a channel dedicated to horror movies, I though it was a great idea and I would be willing to pay extra to get it. However, when I had a free preview of it after buying a cable box, I was very disappointed.
They show a lot of movies that are not horror movies such as Die Hard??? and other action movies. A lot of the horror movies they do show are crap. Therefore, I have decided to not pay extra for it.
