Yes Phlox is awesome and a relatively well developed new alien species. His walking differently is a good thing, it's not hugely obvious but it's a subtle difference that stands out. Seeing his tongue and toenails gets ridiculed but again, actual alien features. How often do we get to see alien grooming.. they never even showed us the Bolian bowel extravaganzas, they only alluded to them!
I like Phlox's friendship with the human scientist, they both seem quite similar in nature and their friendship is believably warm and informed by their mutual scientific curiosity with their jobs and each other. The Denobulan marriages are also cool, FINALLY something different comes along. Okay this was alluded to again with Bolians but we never saw it. With Phlox we meet one of his wives and hear the natter about varying spouses.
Phlox is witty, urbane and after a time more invested in this interesting new space faring species than I suspect he thought he would be. It works. He likes Chinese food. He loves animals both as medicine and pets. He's a good man and he's not human.
blah blah.. one of my favorite ENT characters.
Also they waited until almost the end of the series to show us his alarm reflex!
except for the "Dr. Doctor" fiasco, which , like Tatv I pretend like they don't exist. I hated Guinan...don't know why , except, maybe it was just transference of my Whoopie hate.
