This is my first David Lynch film and if this is symptomatic of his style then it may well be my last TBH. Not my taste.
I would say that it's on the weirder side of his stuff. Lynch is a really talented storyteller, and he's much more than just "I'm weird to be EDGY!!!".
If you want a non-weird Lynch, I would highly recommend
The Elephant Man. It is marvelously acted and wonderfully directed, and it's actually my favorite film of his. There's no "What is real?!??!" stuff. I haven't yet seen
The Straight Story, but it is also a, well, straight story.
Going up the ladder of ones I have seen,
Blue Velvet is weird but has an easier to follow central story.
Lost Highway is weird and has some of the not-explained stuff. It's probably my least favorite of his films, but it's not a bad movie.
Eraserhead is WEIRD. But, you know what, it's very clear from an emotional point of view. There's a mutant baby and a small woman who lives in a radiator, and yet I never felt like I wasn't able to "follow" the film.
If you want something where the weirdness nicely intersects with comedy, I can solidly vouch for the first season of
Twin Peaks. (Warning: the show will make you hungry for pie.)
