I find it odd to buy the show without seeing a couple first... at least one to get some idea. Don't you have some way to rent or stream these, or does that get into the not-in-your-country thing?
I suppose you can see samples on youtube, but "best of" or highlights can be misleading.

I loved Cheers, but with a large cast it can be uneven sometimes.
I thought Seinfeld worked because once you are familiar with the characters, it was a combination of the expected and unexpected. After seeing all the shows a few times it loses the unexpected.
