Firstly, every other Enterprise so far was the pinnacle of Starfleet engineering. With the G they spent an entire season telling us what a rustbucket she is. So no progression here. Secondly, we have the botched up and contrived background story of the refit. Was it just some raw materials or more as dialogue suggests when Picard referes to her as Riker's old command. Thirdly, it doesn't make much sense that Starfleet thought NCC-80102 did something so impressive that its successor deserved a prefix, yet has no qualms erasing the name and registry. Fourthly, I'm not a fan of "Class Roman Numeral" designations. And lastly, minimal effort was made to bring the 23rd century Shangri La class to the 25th century so it looks oddly out of place. So, basically everything about this ship just doesn't work out. It's the biggest mistake they made this season IMO.
