The use of symbolism is used to the entirety of the episode from Names to Items to people. The world is different and you have to look into the cracks in order to understand. Its all there for a reason and are very in line with the cryptic quotes spread throughout.
The characters show certain emotions and actions that should some importance to the entirety of what's happening. The new Laura and her strange behavior towards Cooper, and the things she says. Dale Cooper and his slightly more aggressive manner towards others. The cynicism in how the other characters are portrayed.
The emotions that the scenes themselves show. The car scene being a big contender to this. The bleak, cold and cynical feel from every character, environment, tune, and angle. You don't like anything or anyone you see and it makes you feel like whole world is going after you. A feeling that is the complete opposite to twin peak's tone. While yes it's usually creepy in Twin Peaks, but there was always something that countered it like a funny quirk. That quickly dissipates once they get into this world with not even Dale Cooper to push it away.
All and all, I loved it. It's filled to the brim with dark atmosphere and symbolism to pick apart. It'll keep me occupied with everything it offered and ideas of what's going to happen next. Give it another chance and see what you can find because this is deserving of many viewings.
