I’d say the subject line’s pretty clear. A couple of criteria I’m sure everyone will start ignoring by post 5:
By “long-running” I mean lasting four or more seasons.
Try to restrict yourself to shows that sucked for more than half their run. F’instance, I think the last three seasons of The West Wing were vomitous trash, but the four Sorkin years outweigh them, so it’s out. Likewise, don’t list Star Trek: Voyager unless you think it blew chunks even before Seven of Nine was introduced .
No reality series. They all suck, just in different ways.
Worst long-lasting drama: Seventh Heaven.
Oddly enough I liked this show some years back. The mom was cute, the elder daughter was clearly an incipient hottie, and Simon & Ruthie were funny as hell. But as it’s grown older it’s grown duller and preachier and oh-my-god it sucks. The acting couldn’t be more wooden if they replaced Stephen Collins with Treebeard. Jessica Biel has done nothing wiser in her life than running far, far away from it.
Worst long-lasting action-adventure series: Charmed **
They regularly show Alyssa Milanoa and Rose McGowan half-naked. Not even that helps.
Wost long-lasting sitcom: Family Matters **
Originally planned to be shown exclusively on the television network of Hell. Satan refused; he said the damned souls had already suffered enough.
