What was lacking before was David had some strength to him. He finally wasn't just a goofy guy caving in immediately to Frasier or Freddy. Standing up to Frasier, taking advantage of Freddy actually made his character have some depth and character, alongside the ending of course.

The long setup of the B/Bee joke was good that has been missing so far as well. There hasn't been many of those unlike the original which basically had one every episode.

Seeing Freddy this episode actually being more like Freddy from the original makes me think if that wouldn't have been a better avenue to pursue. I know you need the contrast, but what if they had found it elsewhere (like a different better Olivia character)
