I have now read the entire series. Still not sure how I feel about it. On principle, I feel that mixing predators and engineers seems a little lame. It somehow demeans the Engineers as our theatrical creators. However, if one were to write a story about predators and aliens and engineers, I guess it should be pretty much as dark horse did. It was a fun read with ample twists and surprises. Galago is irredeemable and yet you he's so compelling. Eldon was really a weird and risky creation, but I think the writers and artists did a pretty reasonable job with him. I will really enjoy retreading this series when the TPBs come out. I hope that there will be a big omnibus as well as otherwise Omega would be left out of the TPBs.
I just hope we also get a set of comics which separates the Aliens world from the Predator world. Sorry, but the AVP films ruined the AVP idea for me.
