That's a good problem for the line to have. I'm a lifelong Star Trek fan, but my one ongoing complaint is too many humanoid species. They tried to explain it once as being an ancient race that seeded humans on planets throughout the galaxy, but I really dislike that ret-con knowing that most space fiction chooses humanoids because it's cheaper and doesn't alienate the audience as much.
I don't like Farscape as much as Star Trek, but I REALLY loved that show due to how alien and varied the species were. The Cosmic Legions figures thus far are even more alien than the Farscape characters, and I really respect that about the line.
