Yeah. C-ticket really, although some D-tickets could apply. A ride that's there to help capacity and fill out/add flavor to an area, but not intended to be a headlining attraction.
It's really about expectations rather than the inherent quality of the ride. If Tron wasn't incredibly expensive and hyped as a major addition, it would be easier to ignore some of its flaws. It's sort of the opposite of NRJ, which would probably be considered a relatively good ride by more people (it's certainly not perfect and has some major issues, but has the lush detailing and sense of physical space that many WDW rides have lacked in the past couple of decades) if it wasn't in a land with only one other attraction and a park that has a lack of rides overall. It doesn't live up to the expectations of its wait times, which are long enough to make people expect something more akin to Flight of Passage -- when I was there in January the standby time for NRJ was around 2 hours.
To be fair, it's not a sole headliner at WDW's Tomorrowland since Space Mountain exists. But the ride was built as a headliner E-ticket for Shanghai.
