Well, Roger Ebert weighed in with his review
including this little nugget:
O insists she is blissfully happy with this arrangement, and apparently the guys are, too. I wasn't convinced. When three people share one another, that usually involves only the physical bits. The deep emotional parts are either withheld or missing. My notion is that O likes the luxury and attention, and the lads find her a convenience. This will come to a brutal test.
Now, no one is ever going to mistake me for a poly cheerleader. Ever. This is the most work I've ever put into a relationship and that sort of commitment isn't for everyone. Still, Mr. Ebert, the sort of arrangement I have with my men is definitely one that has deep intellectual, emotional as well as physical underpinnings. It has to otherwise it wouldn't work. Methinks he's spent just a leetle too much time in the Midwest.
