I was thinking it'd be good if we could also add our ratings on a 0-10 scale for movie series with the installments all going in order of release.

Okay, sounds like fun. My rating is based on the year it came out, as opposed to a rating for all-time. I give points for originality; which obviously doesn't hold for all-time. The all-time rating would change marginally.
