My rewatch is still going. They found Earth...well, that didn't go very well.
I'm still not sure why there's a lot of disappointment in how the series ends, but I may just have not hit that point yet.
I can't say there's really any characters in this series who I like. They're interesting, and there are times when they're likeable, but they also are total jerks at various points. I think Helo may be my favorite, as he seems to show a morality that some of the other characters lack. I want to say Tyrell as well, but I feel as though I'm forgetting things he's done that have irked me.
No spoilers please!
