Not only that, but he turns into crows. They're probably smoke crows, but still. That isn't the worst of it though.
They have him possessing people, but instead of him sitting back as the boss and having his minions do the dirty work, he does the dirty work himself. He possesses Glorious Godfrey instead of Godfrey being one of his servants.
Things start to look up when he goes to Club Desaad, which is an S&M club. Desaad? Owning an S&M club? Smallville got something right. But instead of Darkseid being there to observe humanity's deviances and perhaps exploit them, he's actually there to be dominated. Ah, no. If Darkseid is going to indulge in something sexual, he's going to be the one doing the dominating. Desaad on the other hand would, but Smallville clearly didn't think of that.
When Clark asks Kara why Darkseid is so powerful (I missed how Kara knows all about Darkseid if they said it at all), Kara responds that it's because he can see your fears and doubts. That's nice, but there's also the tiny matter of the fact he's a GOD. She also says that Darkseid cannot possess a human who is pure of spirit, which completely contradicts Darkseid's resurrection in Final Crisis.
Then you have the Smallville-isms that you would expect from the show. The eyes of the person he possesses turn black (an effect hijacked from fellow CW TV show Supernatural), the voice of Darkseid is digitally altered to sound deeper, there's a pun on the name, and instead of being called Darkseid, he's referred to as "The Darkness" or "The Dark Spirit."
Even though the comics provided a means for Smallville to use him and the rest of the New Gods on their budget, I knew they'd turn a blind eye to that and do Darkseid their own way. I knew they would butcher the character, but they continue to surprise me with just how badly they can fail at bringing a character from comics to television.
