FJ, Flight of the Passage, and Gringotts are the model for how an e ticket attraction queue should look. They are probably 3 of the best queues in the world. I do like several other queues at Universal as well, including F&F, Transformers, and Fallon.
Hagrids was mostly refurbished from the Dragon Challenge / Dueling Dragon queue to save money. It would have taken more time and cost more to build a queue to the level of quality of FJ / Gringotts.
With that being said, the queue for Hagrids is significantly better than some other recent attractions (I'd say it's on par with Skull Island):
