10 Iconic Movies That Were Initially Critical Flops

10. National Lampoon's Christmas Vacation

After trips to Wally World and Europe, the third adventure featuring the Griswolds had them staying at home and letting their quirky relatives come to them. As expected, many hijinks ensue when both sides of the family are put together in one house for an extended amount of time. Much of it is quite entertaining, though the attitude towards animal welfare leaves a lot to be desired.

Now generally considered to be a Christmas favorite, upon its opening in 1989, the critical response was not very enthusiastic. Critiques included that the jokes were becoming redundant the third time around and that the family wasn't so easy to like anymore.

Over time, and many airings on television, perceptions of the film began to change. And it's also noted for the quality of its cast, with Chevy Chase, Beverly D'Angelo and Randy Quaid joined by a supporting cast including Juliette Lewis, Johnny Galecki, Doris Roberts and Julia Louis-Dreyfus.
