Oh I agree it's an overrated show and as a young teenager I hated it but I love it for it's plot and stories. ;)
But the movie should be good and an installment for fans due to the fact there is so much stuff packed into it...
So due to the above spoilers (which I don't recommend looking at if you don't want to know what they are as they will spoil a lot for you!) I really want to see it. =D
