So what makes art good? How about music? Or movies, or books? Most anyone who reads a newspaper spends a fair amount of time being told what’s good and what isn’t by supposed experts in the field, but how do the critics draw their conclusions? What’s the frame of reference? The Denver Post’s critics get together to offer readers a look into their world, and the results are as diverse as the writers themselves. TV critic Joanne Ostrow sees occasional quality as a welcome relief from the broadcast wasteland. Art critic Kyle MacMillan says that all great art, even the topical kind, can withstand the test of time. And rock critic G. Brown thinks that, in an industry dominated by fakes and puffery, real quality is found by looking for the musicians who make you believe what they’re singing.
