The good: Jorah recognizes that Dany's older brother is a complete psychopath, abandoning his service to Viserys and pledging himself to his khaleesi early on. Jorah would, quite literally, give his life for Daenerys — he overcomes a deadly disease and traverses the entire world purely to win her heart. He's certainly the most consistent figure in Dany's volatile life and gives her plenty of solid advice when she gets a little too crazy with her ideas. We doubt that anyone in Westeros thinks more highly of the dragon queen.
The bad: The banished knight's love for Daenerys is, honestly, a bit creepy. His feelings for her begin when she's barely a teenager, with several decades of age between them. Their relationship is more uncle-niece until he starts aggressively pursuing Dany, which gives many fans the heebie-jeebies.
Not to mention the origins of his relationship to Daenerys; Jorah acted as an informant on Daenerys to Robert Baratheon, knowing that the king planned to assassinate Dany. While Jorah eventually changed his ways, he also hid this fact from Daenerys for years, ruining her trust in him once it finally came to light.
Overall, while we love Jorah and appreciate his dedication, he's better off remaining firmly in the friend zone.
