If the showrunners learn from their mistakes and actually fix the myriad pacing/characterization/dialogue issues from season one, there's a slim chance they might be able to turn the show into something half decent.

Now that they've got all the pointless mystery boxes about the identity of Sauron/The Stranger out of their systems, they can hopefully leave those far behind as well.

I really want it to be good, but I have my doubts after season 1. That being said, this teaser seems surprisingly coherent. I know who the bad guy is, I know who the good guys are, and I know generally why they are all fighting. That's already a pretty big improvement.

That shot of galadriel, elrond, and those other people in the fog gave off a bit of a "fellowship" vibe.

I didn't finish the first season. I couldn't keep going. I probably won't give the second season a chance.
