Beck is quite the puzzle.
On the one hand he can be quite insightful and visionary. Or, at least, he used to have the capacity for such things.
But on the other hand he is incredibly susceptible to muddled thinking. In my opinion, speaking as a more or less fundamentalist Christian, nothing else explains his connection to the LDS religion. The LDS is, to me, nothing other than a heretical cult with its beliefs made up out of whole cloth by a polygamist con man. When a "thinker" (such as Beck claims to be) buys into the ridiculous (and easily disprovable) notions of the LDS religion* they are (again, for me) immediately open to skepticism regarding their ability to reason. So...I have never fully trusted him. Yes, he has done yeoman's work on exposing the progressive/utopian agenda. Good for him. Many years earlier he also did a very comprehensive expose on scientology. That was about when I started listening to him and I thought (at the time), "Wow, here is someone who gets it and isn't afraid to tell it like it is." And then I discovered that he was a mormon and just like that about 90% of his credibility was out the window with me. And it always has been.
Another thing that has periodically annoyed and disgusted me are his descents into abject emotionalism where he freaks out and/or begins sobbing over (fill in the blank because there doesn't seem to be any rhyme or reason to the topic selection that sets him off). He is somewhat neurotic in this respect. You never know which Beck you are going to be subjected to on any given day.
I listen to him sporadically, more or less, to keep myself abreast of things from a culturally conservative perspective, because he is (like it or not) part of the spectrum.
The problem with Beck is the same with any so-called "leader" and that is that they are human and vulnerable to human failings. And the bigger they are, the harder they fall. Beck has "grown" himself into a "leader" of gargantuan proportions and demonstrates for those willing to see that he is far from perfect. Follow anyone, invest yourself in anyone at your own risk because as surely as the sun rises in the east it is only a matter of time before you are let down.
*which I won't go into...you are free to look them up.
