OK, first, it's Danielle Steele, so take that into consideration. Characterization is one-note, the acting isn't all that awesome, and honestly, if you're checking it out here twelve years after the fact, it's probably because you're a fan of Joe Flanigan's work on Stargate: Atlantis and you want to see what else he's done.
Having said all that - I kind of love this. Flanigan is very sweet as the token gay brother, all shy glances and lowered eyelashes. Jaclyn Smith is no better than you expect, and as the above reviewer said, the clothes are just wrong. BUT, if you're in the mood to sit down with some girlfriends for a pizza-and-movie night (beer optional), and watch a movie that will make you laugh and unexpectedly get a tiny bit emotional, this is the one. My friends and I have watched it several times, and the love just grows.
