It's Flashbeagle, Charlie Brown 4K Review
Now, I love the Peanuts specials. Like most of today's adults, I grew up on them and cherish them. But this one, well... this is just one man's opinion, and feel free to disagree if you wish, but it's arguably the worst of the bunch. The whole Flashdance stuff REALLY dates it (most of today's kids wouldn't understand it), and Peppermint Patty's whole "I'm in shape!" routine tends to get really annoying after a while. Plus, the whole story is kinda weak by the past shows' usually high standards. Stick with the holiday shows, or if you really want a good non-holiday Peanuts show, track down Someday You'll Find Her, Charlie Brown.

As an interesting side note, if you do watch this episode, listen closely to the voice of Sally... it's none other than Stacy Ferguson, a.k.a. Fergie from the Black Eyed Peas.
