Not terrible, not great. The "what if" behind the plot is rather silly for anybody who knows anything about DNA or how long sperm is actually viable, but if you can suspend your disbelief (a lot!) I suppose it doesn't suck. I had to roll back the ages of the main characters by quite a bit to believe in most of what they were doing, though, because they just didn't act like any 30ish men I would want to know. Then again, they are four never-married 30ish men who have spent their entire lives in one small town, so maybe their boyishness will seem realistic to someone.Many of the scenes would make for interesting visual effects if they were translated to the screen, and I'm not even a visual thinker.
