It's 6.5 out of 10 stars for me for this dramedy that should have stayed nearer to drama toward the end.
What's great about it: Williams' performance. I don't think people were ready, at this time of his career, for a nuanced performance, but that's what this is. He breaks into being the crazed Williams of talk shows only twice, and briefly, during this film. Otherwise he is convincing as a middle-aged car salesman with complicated relationships and the absence of a long-term plan. His excellence at sales isn't limited to cars; he can talk many women into bed, and that's his downfall.
Robbins is also good as a stupid, jealous husband with a gun.
What's not as good: the supporting characters at the car dealership were under-written. The Chinese restaurant and police captain stuff was awful. I can't stand Fran Drescher, and I can't stand her here. (If you like her, you'll like her here.) The dog she's carrying was used too much, and I realize the yappiness was supposed to heighten the tension, but mostly it made me want to look for my own gun or consider shutting off the DVD. I never did see that his sacrifice during the hostage-taking was fully motivated. (Seems drastic to be willing to die just to avoid a stressful day.)
I did like the character of the ex-wife and that of the wannabe awful clothes designer girlfriend #2, played well by Lori Petty. Also, I liked the bizarre opening scene which is in the middle of a funeral procession. There's a how-to writing book I once read that said, bring all your characters on stage with their (attributes) flying. This opening scene did just that, so kudos to Ken Friedman.
