Mike Binder is no Woody Allen..
8 February 2002 | by hrlaserSee all my reviews

If Binder sold HBO on his pathetic "Mind of the Married Man" series based on having written and directed and starred in this film, it wouldn't surprise me, as both had a lot of the same elements and ideas, and both were equally lame.

Binder is no Woody Allen. For that matter, he's no Albert Brooks either. He's not even a Gene Wilder, about the most unlikely actor for a sex farce I can imagine, but then maybe women see some kind of appeal to that sad puppy personna..

But someone must think Binder is funny, else they wouldn't be throwing money at him as HBO did..

Sex Monster (don't let the title deceive you.. this isn't a movie about Godzilla humping Tokyo).. can be taken as a prequel to Mind of the Married Man with one exception.. instead of fantasizing and visualizing in his mind, other women in bed with his wife, this film explores the possibilities in a very tame way. If you're looking for Mariel Hemingway nude, forget it. In fact for a sex romp, this film has alarmingly little nudity at all. Lots of tease shots, and women moaning and groaning behind a closed bedroom door, one almost topless shot in a swimming pool, that's about it.

Mariel Hemingway, still gorgeous after all these years, and quite a screen presence, plays Binder's straight and faithful wife to whom he pitches the idea of a second woman in bed with them.. most every guy's unfulfilled fantasy.. at first put off by the concept, she aims to please him, she warms to it, then dives face first, as it were, into it, to the point that he got what he wished for and now he wants to un-wish it..

The way this film was shot and edited reminds me of an even tamer version of the way "adult" hardcore videos are presented on tape, versus how they end up on channels like "Spice" where you see the tops of a lot of heads bobbing up and down..

I kept waiting and waiting for the big payoff.. but this is a sex film with no "money shot", both literally and figuratively.

It's a one line joke that somehow got stretched to an hour an a half, and it moves at such a glacial pace that I actually fell asleep the first time I tried to watch it.

Mariel Hemingway is still beautiful, still talented, and she deserves to be pitched much better scripts than this one, and someone needs to tell Binder that his fantasies are simply just not rip-roaringly hilarious..
