Holy shit, your family too? My mom had the original trilogy on video, then later got the VHS box set for the re-release in 1997.
Personally, I thought TPM was meh, AoTC sucked for the most part, but RoTS, while not as good as the OT, was for me at least, the best of the prequels, although that might just be my inner Vader fanboy speaking.
