I've had that with them, too. While it's true that they're not super detailed, I'm also not an expert in every field, and in the majority of articles I found it a good balance. But years later, perhaps I've moved beyond that.

I subscribed for several years until I got tired of their political agenda. I think the straw that broke the camel's back was a feature article on cleaning up landmines in southeast asia. Now, surely this is an important topic, but it's not what I come to a science magazine to read about.

From there I moved to American Scientist magazine, which I found a bit deeper in many cases, and much better regarding editorializing.
