I just finished the series last week, too. I stumbled across it at the library, although I had a vague memory of having heard of this show's existence. I got the Season 1 DVD...and quickly got hooked. There were things I didn't like about how it ended...but I have to really give them credit for creating something that takes a well known character, and having it feel fresh throughout.
One thing I'm wondering about that refrigerator: would it have had an evaporator fan inside? I'm sort of guessing those came along later, but in one episode I thought I heard a fan running when the refrigerator opened. Maybe I was wrong--I was going to go back to that scene later, but totally forgot until this came up...
