I’d call it faux Lynchian but I get What you’re saying. I thought they stretched the pacing out too long in both seasons. But overall I still enjoyed it.Like all series I get interested in, I got in late watching Severance, but I am really enjoying it. The pacing is a little slow, but it is unfolding like a fever dream. I really like the visual style and it has a little bit of a modernized David Lynch feel to me.
If you like the visual style you should look for the movie Playtime by Jacques Tati, which the style was based on.
