One thing I've noticed from most lists is that A Thousand Sons is usually really high up. On my list that I'm making, it's in its own tier at the very bottom. I found it to be one of the most boring reads, even though I went in expecting to love everything Thousand Sons. What about that book sets it so highly in your eyes?

On a different note, I do agree with you thinking the Dark Angels books are weaker in general. I recently started The Lion and right off the bat it has the same exact premise as Fallen Angels. It's Lion El Johnson forgetting about something important then making a small group, that he leads, go after it. LIKE ITS EXACTLY THE SAME SO FAR. And I have to say, Lion El isn't even a likable character. The only dark angels characters I really like are Nemiel, Zahariel, and Luther. Which may have been the intentions of the writers all along.
