Shows are popular for a reason. Not just "because."
"Popular" is a FACT (meaning that a lot of people are seeing this show). That's a fact.
"Good" is an OPINION, and has nothing to do with how popular Wicked has become.
So... are you asking if it's good, or why has it become so popular?
Wicked became popular because it struck a chord in many people (no, not just fangirls). A whole lotta folks see themselves as Elphaba (to some degree). Their good intentions are misinterpreted, they are not accepted by the mainstream, they are pushed aside in favor of "the obvious choice," etc. I'm not saying they're RIGHT in their personal assessments (if everyone is the "poor misunderstood outcast" then who the hell is "mainstream")... Regardless, they see some part of themselves as her.
Whether or not you like Wicked as a musical isn't really the point. The story is incredibly powerful, and so is it's message.
In other words... it WORKS on the most important level of all. It "connects" with the majority of the people who see it. That's why people are going, and going, and going...
I also happen to think it's good... but hey, that's just me. And it's also beside the point.
