I had a similar reaction! Back in 2006 or so. I thought all the "I say!" stuff was pretty embarrassing and cringeworthy and I didn't get the humor. I couldn't believe what "that House actor" used to look/sound like. But I finished the episode, and then the series, and now I can't see him as anything but extremely adorable and handsome in it. And I came to appreciate the humor a lot.
