I'm pretty cold on the Destiny trilogy.
Didn't like anything to do with the Caeliar & their story thread (especially deanna's behaviour), the aventine or the resolution of the conflict(would have preferred a "the return" style resolution that would have enabled the borg to have carried on, but in different factions that could have had big differences). Also I disliked the Thalaron conversation between geordi & picard. Geordi's side I get, but picard backing down given the situation felt pretty absurd and really broke me out of the story.
I loved the exploration through the subspace tunnels though, that was a lot of fun.
