Great analogy! I was the same way with Inception. In the end, I decided that there simply wasn't a right answer to Inception. If you believe the spinning top fell at the end... you were right. If you thought it kept spinning... you were also right. Part of the brilliance of that movie is that there was an equal amount of evidence for each opinion. Normally I like to fight until I win an arguement. But with that, I just threw up my hands and said, "I can't possibly prove either side is correct". I chose for it to fall.
