I think you’re getting very confused about degrees of criticism and broader context. SWL looks very promising. That said, given the prominence of the franchise (and the fact that DL wanted at least one extra attraction), it is fair to suggest SWL could have used more rides. This is a relatively minor complaint. The lacklustre nature of TSL is a much more glaring target for criticism. In fact, the justified criticism of TSL also adds intensity to the criticisms of SWL. Together, TSL and SWL (and MMRR replacing GMR) do not fix MGM, which they were meant to do. SWL and a Pixar Land with an e-ticket would have come close. SWL, two new e-tickets, and replacements for shows that are over two decades old would have fixed it.
Potter saved Uni, but IOA was already a better park then MGM before it opened. Any calls for more rides in Pandora stem from the fact that RJ is barely a ride and that AK, while WDWs best park, needs a couple more attractions. If you added a new area to AK now, one e-ticket and a c-ticket or show would be fine. Context is key.
