Congrats! Are you going to get the other seven Trek movies now?
When you decide to increase your collection, it might be good to check out Blu-ray review sites (highdefdigest.com, bluray.com, etc.) -- not for reviews of the movies themselves, but for reviews of the video and audio. You can find out a lot about older titles (Robocop) that the studios didn't bother to do much of an upgrade of, or newer titles (Gladiator) that have video issues.
