We will always have a soft spot for Vince Vaughn and Jon Favreau for giving us “You’re so money” and “Baby’s all growns up.” And we want to love everything they’ve done ever since. But often, we can’t. Hello, Made? Likewise, we want to love “Couples Retreat” — after all, it sounds right up our alley: four couples, all friends, dealing with issues of commitment, love and sex. But if the trailer is any indication, it’s riding that fine line between brilliant and bad — and we fear it and its two leading men may fall on the wrong side of that line once again. We won’t know for sure until October 9th when the movie hits theaters. But we’re pulling for them. What’s your guess?
