David Lynch's on minimals.
It's a shame everyone chewed at the end. Sometimes it is better to revisit the film to understand the unsaid, than to listen to the same explanation several times.
First of all, you lose all the high of the "A-ha!" effect, and secondly, you start to think that the target audience of the film is weak-minded, and you are one of them.
The authors apparently were so afraid that their film would not be understood the first time (and under a large dose of popcorn and cola), that they overdid with the number of Doctors Watsons and voice-over Caps.
I could've done a good job. But it's nice to watch. The film deserves a good rating.
