My mentality isn't "if it's CGI, it sux".
Okay good. It seemed like there was some wholesale forgiving of LOTR's bad CGi while at the same time ignoring the stupendously good CGI (like Smaug and Gollum as you mentioned) of the Hobbit.
I'm good with CGI as long as its:
1. Mo-capped
and
2. You can't achieve the same effect practically.
It's not like Richard Armitage and Orlando Bloom were just swinging at air or anything. They put "Big Mike" in a full mo-cap suit, complete with crash helmet, and had Bloom slamming his real head into a Lake-town post over and over. Then they just painted Bolg's skin over Mike. I'm fine with that because the "reality" of the interaction came through in the final film IMO. Just like having Andy Serkis actually be there as Gollum and so on.
What I HATE is when animators half-ass things by "winging it" (no mo-cap) or when people are animated that can look just as good with real suits (AOTC clones I'm looking at YOU.) But Azog and Bolg's final designs couldn't be achieved with make-up anymore than Gollum or Smaug. They tried it with Azog and we got weak-ass Yazneg. Bolg's "real" original look was pretty badass but I can understand why they would change him to CGI since he should match the look of his father.
I'm surprised that you're basically writing off this trilogy. It's like these movies are your Middle-Earth TDKR or something all because of how they were filmed in a technical sense. Its' not like these movies betrayed the core persona of the main characters (you didn't have Gandalf abandoning the battle so he could go live in Italy with Galadriel, nor were the epic villains randomly turned into whipped stooges at the end.) PJ gave us heroes and villains that easily could have stepped out of the LOTR films but he just wanted to use CG, 3D, HFR, etc., to present them in a more fantastical way.
Even if you do want to say "Yeah, but that's what Lucas did. He went overboard," it still isn't the same. Even if there was "too much CG" (which I disagree with) that wasn't really the downfall of the PT. The PT's downfall was its awful writing, casting, and just overall stupidity. The twists were dumb (Anakin builds 3PO) the characters from the OT that were revisited were mostly lame (Fett, Vader, etc.) and it ruined twists and made moments in the OT more lame if you take it all as one story.
But The Hobbit didn't spoil any twists of LOTR, everyone from the LOTR that appeared in The Hobbit (Gandalf, Elrond, Galadriel, Saruman) was just as badass and cool as they were in the previous trilogy, and all the newcomers were well cast and well written. You might not have liked the look of Azog but he was a badass and never made any "stupid" mistakes. He was simply outfought at the end.
