I saw an ask on here earlier for someone else. But I want to give an answer as well. There is one thing that the series has done better than the movie, or the book, in my opinion.
(Spoilers for all 3)
That one thing is to get Lestat's poisoning right. In the 1994 IWTV movie, Claudia killed two boys with laudanum and presented them to Lestat as a peace offering. Now, this might have been changed in later books, which is something I know Anne did. BUT, up to that time drinking from the dead did not kill vampires. You did not drink from a living person until they died "lest the death take you down with it". And this was very true for young vampires, but seemed to be less true for older vampires. But dead blood was not a poison. Also, Lestat would be far too smart to not realize that the boys were dead! No heartbeats, no breathing, not a single thought in their heads, certainly Lestat could tell a dead person from a living one.
In the book, Lestat drinks poisoned blood, which made him weak enough to be stabbed. It was more plausible, but still it was a gift from Claudia. And I think Lestat would have been smart enough to see a set-up like that from a mile away. Also, I think he would have smelled the poison, if not before he drank the blood, then as soon as he tasted it.
But in the series, there is a huge party, Lestat is drinking from drunk people all night, and vampires do get that effect from the blood. Plus, the poison is put into a person that Lestat loathes, and to think his blood might have tasted off, wouldn't have been an immediate signal to stop, because Lestat wanted so badly to kill him. And Lestat, in his reasonable paranoia, has made another vampire who can hear Louis' and Claudia's thoughts. This gives Lestat far more credit for his intelligence than either the movie or the book. Yet, he still underestimates Claudia's deviousness and Louis' powers of observation. I can believe that he really thought Louis and Claudia would not notice Antoinette's constant presence. I really believe that he thought he'd gotten away with telling them he had killed her, when he had not. And if he didn't realize that they knew about her, there is no way that he could have known that they were communicating a fake plan to each other about who would be poisoned.
This scenario does not make Lestat look stupid. It does play on his arrogance, sense of superiority as a vampire, and his love of Louis and his anger at anyone who would try to humiliate him or take advantage of him. It tracks for me. In fact, earlier in the scene I thought, 'Aw, Lestat, you should have let Louis kill Tom!' Little did I know.
So I have to say, the series did it much better.
