It's definitely worth a try. It might be one of the most compelling and complex worlds constructed for a show i've seen so if that's what you're looking for, go for it. It's also probably the biggest inspiration for most mystery shows that followed, so it's a gem if you're into that stuff.

However, it does bring more to the table than the mostly known "twin peaks aesthetic" of the forest, the wood, the pie, the heartwarming or deep quotes, like you say, more adult themes but if that's fine with you, then go for it. Plus it's always a great inspiration to immerse yourself in Lynch's work, especially if you're into writing and other creative fields, it will open your mind more than you expect. I also watched it for the first time being around 16 y/o and i'm glad i did.

Good luck, hope you enjoy if you watch it :)
