Has live-action nuTrek been able to create any interesting aliens and creatures?
I don't think so.
Live-action nuTrek has access to FX that makes previously inconceivable aliens and creatures possible, but what has this FX actually been used for?
We've gotten whales, T-rexes, xenomorphs and puppets...nothing really original, alien or interesting (IMO nuTrek's best aliens appeared in "Children of the Comet").
Trek has admittedly not had a good track record when cooking up truly alien aliens - for every Horta, Vox Sola, Crystalline Entity or Space Amoeba there have been a dozen Forehead Aliens - but with CGI, the possibilities are now endless. IMO the writers should be making an effort to cook up multiple truly weird species/organisms every season. After all, part of the fun of scifi is speculating about different forms of biology, and different ecosystems.
