About a third of the way in, you'll find yourself asking, "WTF did I get myself into?" and ponder whether it's better to cut your losses and shut it off, or continue on and hope it starts to make sense.
By the end of the flick, you'll probably be glad you stuck with it, but you'll still be asking yourself, "What the FUCK did I just watch?" It will start to make some sense, and you may actually come to find out you really loved it. (Or at least loved it enough that you'll write a blog post about it and recommend it to your friends.)
