Foundation is definitely a must watch for any sci-fi fan. I never read the source material and it seems that most of the people who don't like this are mad because it's not exactly like the book. Some people don't understand that these shows and movies are adapted or based off the source material. Some parts are a little slow and throws the pace off a little as it builds its world but not slow enough where it makes it bad. The visuals are as good as anything you'll find on tv. You can tell they put a lot of money into it and it shows. This also has some great characters that will make you invested in the show and actually care about what happens to them. Foundation has ended up surprising me then just about any show that I can remember. It really has become one of my favorite sci-fi shows that I've ever seen.
