I stopped watching 5 minutes in and was immediately compelled to write this review, and I don't usually write reviews. The two main characters are obnoxious, self-centered, and oblivious to common decency. Their behavior is so over-the-top inconsiderate and mind-boggling dumb that even if people in real life are this dumb and inconsiderate, then this movie is more depressing than it is fun or entertaining.
For example, one of the women sits in three different movie theater seats before she figures out that it's her water that broke, and not three different seats that were wet before she sat down. Both women thought that it was way more likely that three different seats were wet than it was likely that a woman in her last trimester had her water break. Neither of them checked the second or third seat beforehand to see if it was wet, either. Not to beat a dead horse, but only the pregnant woman's seats were wet... did either think that was a clue as to what was happening? Nope. And then the women immediately go to a restaurant where the pregnant woman leaks all over the floor and chair, and then berates the server who (politely and rightfully) points out that her present condition may not be sanitary given the exposure of her fluids to the other diner's food.
You know those infomercials that go over-the-top when portraying how difficult something is, or how inept people are at simple tasks? Like, a husband who is home alone taking care of his kid while his wife is away, and the husband can't operate the toaster our pour cereal into a bowl to feed his kid... you know, something like that? That's the same feel this movie had. These two women were really, really stupid and unlikable. All I could think about was the poor kid that's going to be born to this idiot... Too depressing to continue watching.
