What do you consider to be the most interesting alien race?

I think Farscape had quite a few of the most interesting alien species, with Babylon 5 a close second.

1. The Pilot
2. Pa'u Zotoh Zhaan (a plant humanoid)
3. Ha D'Argo
4. Dominar Rygel XVI
5. Scorpius
6. Chiana

I loved B5. Belong to a Facebook fan group. The Physics Forum thing about the show I found most interesting is how Straczinski dealt with the FTL problem. Don't build a starship, build a universe the ship can access to get to other points in the galaxy quickly.
