In fact, tonight is the season premiere of White Collar on the USA Network. I can’t personally attest to the quality of the show since I’ve only seen a few episodes of it. However, the fact that the show is on its fifth season says something.

Thiessen’s first major success was as Kelly Kapowski on Saved By The Bell. That show is still on reruns in syndication (the same can’t be said for Saved By The Bell: The New Class).
After SBTB, Thiessen went on to 90210, keeping things interesting as the vampy Valerie Malone after Shannen Doherty’s departure from the show left a possibility of boredom on the Beverly Hills-themed drama.
Thiessen floundered a bit after her run on 90210. Shows like Fastlane, Good Morning, Miami, and Two Guys, a Girl, and a Pizza Place weren’t hugely (or in some cases, at all) successful.
