Never was much for the Barris stalwarts. Newlywed always had pretty much the same formula: Bob reads a question that tries to be titillating but doesn't have the guts to actually pull it off. Then, the husband and/or wife gives a response that's a bald-faced single entendre and/or so far off the mark that it wasn't even funny, just painful ("What's your husband's favorite rodent?" "The saxophone." -- *shudder*). Sure, sometimes there were genuinely funny moments, but for the most part, both of those shows just make me cringe. Not to mention that Dating, at least to me, feels like it barely even needs a host.
Love Connection, on the other hand, was just too low-key for the most part. There just wasn't much of anything on it that made it all that interesting, save for Mr. Two and Two himself. That, and coming up with theories as to how John Cervenka found his way into the announcer's booth.
I saw all the votes for Bzzz! here and thought I'd check it out, since I had never really heard of it until well after the fact. This is just about the right balance for me: it's a little campy and silly (that totally radical, Bonkers-esque "bouncy" font looks more like something out of 1992 than 1997), but it just feels more natural and fun, not calculated and cheesy. Also, it has a more interesting and varied format than most.
