That doesn't mean it's not worth having an opinion about, including if the opinion is critical, including if it didn't "work" for some which can be true while acknowledging (as I have) that it worked for most and worked in the sense that it was a successful run.
Also it not being one of the greatest works of the musical theater does not at all mean it isn't worthwhile or fun to analyze and dissect it and either of its major productions (Fosse or Paulus/Fosse-Walker/etc). If I (and you, I assume, and most) hadn't been so taken with the Fosse original in the first place, if it hadn't been stimulating as a musical and as a staging, then we wouldn't be talking about it. But it was, luckily, and we are. I don't get when posters here bemoan or resent discussion that doesn't just agree that something that was successful therefor "worked" for the material, or that if it isn't a masterwork why bother arguing. That's not why I'm here.
