ELI5:Why some accents are loved while others are frowned upon?

Is some logical reason behind it, which makes the accent likeable.

It can be influenced by your own language and experience, but in general there's two contributing factors. 

First is our expectation: "Frrench is ze lang-wajj of r-r-ro-MANCE!", for example. So if we're a bit romantic at heart a French accent may make us have a positive response. This has been influenced by the media too - certain languages and ways of speaking are often associated with villains in movies, for example; others are often associated with nurturing characters (Mary Poppins). And some are unfortunately tied to more redneck or primitive feelings (Disney Goofy's "Gawrsh!" and "Hyuck!", for example) versus the sophistication of a Cary Grant or Hugh Grant.

But a big part of it is some languages have a cadence and flow in them that is less guttural and harsh than others. Compare the "lilt" of an Irish person's speech against the guttural harshness of a German one or the abrupt jarring of a heavy Cockney accent. We're inclined to prefer the former due to its smoothness and flow.
