I sure don't hold it against you! And you sure shouldn't be up at 3:00 in the morning! I didn't see the originals when they aired, I grew up watching reruns after school in th 70s. Then there have been the various Star Trek-a-thons in the 80s or 90s where we made sure to tape as many episodes as we could, because we really enjoy them. They've become part of our video library. But that's what happens as you get older, and you have both the space and time to collect stuff.
I can also see how they would appear kind of hard to watch in that "low-tech" way, for people who grew up with more exciting graphics than I did. But maybe you'll have fun over the years as you get a chance here and there to see some of the original episodes!
