It's easy to say, but I don't think the reality bares it out. Critics and snobs can complain about all the live action remakes but the reality is that "ordinary people" - y'know, the people who buy tickets to go see movies - actually eat them up. Even if critical scores are mediocre, they generally have done well on on Cinemascore and RT Audience scores (look at the scores for the live action The Lion King, Aladdin, Beauty and the Beast, etc). And obviously the box office are largely good.
In fact, the biggest misses from Disney have generally been when they've tried to branch into original (or at least non franchise) live action movies. The very thing that people here often suggest they need to be doing more of.
Disney has basically dominated the box office the past decade and it has done so by giving the audience exactly what it wants. And they are doing it with far fewer releases than other major studios. If someone wants to argue that the Iger lead Disney movie strategy is poor, then basically no studio is doing anything right. The reality is that Disney is consistently putting out films that inspire people to spend time and money to see them (and talk about them, etc.) - it's hard to argue that isn't at least a major goal of filmmaking.
