6. Lisa Kudrow
Romy and Michele's High School Reunion Something of a minor classic, this nineties comedy is absolutely terrible and often delivers in levels of mediocre to downright excruciating to endure. Kudrow channels Phoebe and dials it up to eleven in the annoying meter to co-star with Mira Sorvino as two utterly uninteresting high school rejects who pretend they're the inventors of Post-Its. That is a classic recipe for pure nineties mediocrity, and the film has thankfully never really been embraced beyond sporting a prequel in 2005 with the equally irritating Katherine Heigl.
