You may not be able to tell a good book by its cover, but it seems to me that much of the time you can tell a good movie by its opening credits. GATTACA begins with extreme closeups of the genetic material falling off of a man while he grooming himself early in the morning, at the main credits appear with the letter of the genetic code standing out from the other letters. A brilliant opening score is paired with this beginning, and it only gets better from there. Like the opening credits, the entire movie is less about flash and more about substance, depth, and (in my opinion) sheer genius.
