Not a single laugh. There is no comedy in here even on the level of the lamest old sitcom. Some of the attempted humor is stomach turning. There's an extended "joke" where one man is repeatedly drugged while someone tries to push his wife into sex.

The only appeal of this film is seeing a few actors early in their careers, Jeff Goldblum and Deborah Winger. I also spotted an actress who later wound up in TV's Fame and another actor who would be on One Day at a Time. Too bad he's an Italian cast, ridiculously, as a Latino, and a bad caricature with a worse accent too.

Whether or not you like disco (most of it is forgettable and some is irritating garbage) this film doesn't give you almost any good performances. Only two songs performed in a supposed musical. The rest of the soundtrack is generic background. As George Clinton put it, disco is dumbed down funk, both lyrically and musically, like having sex with someone who only does it in one position their whole life.

The great Commodores lip sync for a single song, and it's intercut with awful attempts at comedy. Let us see them, damn it! At least we get to see Lionel Richie before he went solo and did bad pop ballads. For a dance film, we don't see anything close to good dancing.

Donna Summer, yes, she does stand out in an otherwise poor film. See it for her scene and to look at actors early in their career. Fast forward past the rest.

It's Friday L.A. Tony Di Marco (Jeff Goldblum) runs the popular disco Zoo. Frannie and Jeannie are underage girls desperate to get in. Sue drags her stiff husband Dave into the club after their anniversary dinner. Gus and Shirley are a bad match on a blind computer date. Carl and Ken are hopeless in getting girls. The Commodores are performing for a dance contest but they don't have their instruments. Floyd is bringing their gear but he's hopelessly delayed. Nicole Sims (Donna Summer) sneaks into the club and becomes a star performer. Jennifer (Debra Winger) is a reluctant patron who keeps getting hit on.

This is a bad disco movie although there aren't that many good disco movies. While it's not a good movie, it has a great song. It's an iconic song that defined a genre and an era. Otherwise, this is the Love Boat in a disco with less fun. The acting and the writing are inferior. Even interesting actors get lost in this muck.

The sweet feistiness of Donna Summer as disco hopeful Nicole showed her as a natural actress who could have made it in film had she pursued it with more vigor. Not only is she classically beautiful, but she's got personality and charm to spare. It takes a while for her to get her shot but it's worth the wait.

The film as a whole is the Grand Hotel of disco movies, a comedy focusing on the variety of people who pop into a popular Hollywood disco where D.J. Ray Vitte is the equivalent of doctor Lewis Stone in that Academy Award winning classic. He's trying to get through the night preparing for the Commodores to perform, only interrupted by various setbacks (including Summer) while spinning the records. Summer breaks into "Last Dance" 70 minutes into the film, creating the disco national anthem.

Club owner Jeff Goldblum goes around making passes at the single ladies, and one not so single, the unhappy Andrea Howard, married to square accountant Mark Lonow who begins to have a little too much fun after not wanting to go inside in the first place. There's also the two underage girls desperate to get in no matter how, feisty Chick Vennera who likes to dance on cars, and the young Debra Winger who keeps getting hit on by over polyester clad jerks.

While definitely a time warp, it's a happy one, an old fashioned 30's style film with 80's ideals, and a look back at a free time in American culture but before the crash that resulted from in the 80's. Certainly some of the characters here are unpleasant, and you wouldn't expect anything less from such a setting. Once you get past all those polyester outfits and Dorothy Hamill hairstyles, you will be dragged out onto the dance floor and never want the last dance to end.
