I can relate to your late watching of the Office...and I have yet to warm up to it, for some reason. Similar thing happened to me with "The New Adventures
of Old Christine"...caught on late night re-runs & think it's pretty funny. I think if you're not really in the mood to watch something, it just falls flat...but at the
right time, it gels & can be hilarious. I like Julia Louis-Dreyfus far better in "Old Christine" than in Seinfeld (of course she has a bigger part, and that helps, but
I love the entire cast too).
I'll have to think about it more, I probably have a much longer list of these...my taste in movies is seldom for the mainstream fare, so I frequently ignore stuff
when it first comes out anyway.
