I watched every single one back in the day, til the movie came out and I quit cold turkey. The only ones I remember were the vampire pizza boy, the Bobby Darrin song, and the circus freaks in the sewer. Is it worth a rewatch?
I watched a series of the well-received ones (as noted from their episode entries on Wikipedia!) from seasons 1-4 and enjoyed myself, kind of tailed off at an episode involving a talking tattoo
If those are the only episodes you remember, emphatically yes; I (internet stranger) highly recommend a re-watch! From the beginning.
If you're not a big sci-fi fan in general, and aren't looking to forgive a little outlandishness from time to time, and/or don't usually appreciate some dry, yet campy humor, it may just not be for you. But, otherwise, it's very entertaining, especially by standards of modern TV writing.
I probably re-watch it every few years, though admittedly it's less enjoyable here and there, but it ended as well as it could have given production yadda yadda. It has its faults, but they're understandable when following along with a little easily found online trivia. The final, "new" seasons I couldn't get through, though. I've tried, but no. Wouldn't recommend.
Sorry, two sentences turned into many, because clarification.
