Finished Season 2, and I have to say I actually enjoyed it overall. They're still moving faster thru the timeline than I'd like, but meh, I'm fine with it.
I've found it helpful to ignore any kind of "canon" discrepancies mostly by considering that (1) they can't use Silmarillion material, (2) "canon" is a fairly squishy thing for Tolkein beyond the original four books, and (3) you can treat a lot of the rest as "legends" for which there can be different versions. With this as just another version.
Some stuff is a little obvious (e.g., "Grand-Elf"), but the rest has been overall better this season.
I think the first season just had SO much table setting to do that it felt more incoherent. This season felt more focused.
