My Best Friend's Girl is one of those types of movies that really 'goes for it'. It GOES for the corny humor. It GOES for the vulgar humor. It GOES for some harsh-truth humor. For better or for worse; it completely nails it start to finish. Now, the plot is where this movie ultimately suffers - and the ending is so painful that luckily the content before it is good enough.
If anything, the two 'countdown' sequences (you'll know it when you see it) make this worth the watch.
