The Romantic Comedy Option: Love, Actually
You can also take this as a primer for Richard Curtis's just-released About Time. However you slice it, this collection of interconnected stories about love and London and Christmas and friendship features a phenomenal cast -- Emma Thompson! Colin Firth! Bill Nighy! Keira Knightley! -- and enough storylines that you're bound to latch onto a few. Plus a dynamite happy ending.
The Coming-of-Age Option: Mermaids
Cher, Winona Ryder, and Christina Ricci play a roaming family who end up in Massachusetts in the early 1960s, and the mother-daughter conflicts between Cher and Ryder should not detract from the delight of seeing them onscreen together. Any film that can end with a kitchen dance break is the change of pace you need.
The Musical Option: Camp
Performing-arts students and outcasts gather at a summer camp to perform and figure themselves out and scheme and fall in love. The hilarity of watching teens performing musicals like Follies and Dreamgirls is good enough, but there's a beating heart at the center of this movie that's earned it a warm cult following.
The Travelogue Option: Enchanted April
This early-'90s film about British ladies taking time away from their lives was Mike Newell's film before Four Weddings and a Funeral and stars Miranda Richardson, Polly Walker, Joan Plowright, and Jim Broadbent.
The Mystery Option: Clue
Who doesn't love Clue? If you have a little residual Halloween-based need for murder, at least choose this utter delight of a murder-mystery. Flames on the side of your face!
The Classic Option: Duck Soup
Classic Marx Brothers madcap comedy is just the thing you need to start November off right.
