Mini series would have been better

I'm kind of bummed, because this could have been so good if it didn't feel so rushed. So much was left out, and I don't even see the point of, for example, even putting Gilbert in, when it really didn't amount to anything. It's like they felt like they had to put him in (since he's such an important character in the novels), but there wasn't enough time to make anything of it. This should have either been a longer movie, or a mini series, shouldn't it?
