I kinda feel like the slow/annoying parts might be important. You gotta eat your vegetables! But, I often feel like this about film/music/art and it might just be some ridiculous puritanical hangup with no basis in reality I don’t know.
You got to episode 5? I can't remember exactly, but I think it was after 5 or 6 that Lynch wound the weirdness dial a couple of notches higher. I may need to watch it again now.
