Ah shit so I'm still in the "good parts". I've never seen Twin Peaks and I'm wanting to finally watch all of it now that it's completed. I'm on Season 2 Episode 4 and thought it was great so far considering how much flak I heard season 2 got. But turns out I just haven't gotten into the crap yet, I really hope season 3 is worth it.
Season 3 being worth it really depends on your taste. Just keep in mind it is EXTREMELY different. This is both a good and bad thing for me, some people love it.
I think that first stretch of season 2 that you're in now is the best part of the original show. S1 is good but S2 mixes in more darkness and just has a lot of really good high points. The bad part of S2 is really exactly as that guide says, and the finale of S2 is the best episode of the entire thing full-stop.
