I mean, the Disney stuff is kind of overproduced junk. Its inexperienced vocalists mixed with lowest-bidder production for the most part. Some of the time also mixed with actors doing singing without any kind of proper training for it.
As to "Pop music" in general thats a pretty broad question. Songs written with simple four chord progression in basic major and minor keys and Chorus/Verse/Chorus/Bridge/Chorus structure covers plenty of things that aren't at all bad. Defined as Top 40, or Top 100, or what have you there's still a decent number of things amidst the all the lazy cash grabbing, meme fodder (since youtube became a chart factor), and so on.
Of course, the one nod I give to any musician, regardless of personal taste for their music, is if they're doing their own thing. Whatever, do your creative thing, no judge. But if you're a musician getting paid thousands (or millions) of dollars and being held up as a top tier performer to perform stuff other people are writing for you, as is 99% of said pop music, thats where the judgement starts to come in when there's obvious gaps in talent or effort or execution.
That segues into another issue, where its often hard to take pop music at its face value. The guys discussing mainline (NAshville controlled radio) country up there kind of touched on it. If you take what should be earnest experience based sentiment in music, and then mass produce it by committee and dole out to marketable faces to present, it strips a ton out of it. Even if the performer has some sincerity behind the tone, the curtain on thats been gone for awhile and its hard to take it as actual emotion. Country is a genre that essentially is built on storytelling, so its taken a huge hit from this effect, but it seeps into other genres as well.
