Like many epics, it was long, there were generations of characters involved, and it took place during an interesting and tumultuous historical epoch, but it didn't strike me as terribly inventive and I found it exceedingly repetitive.
It honestly wasn't bad, it just wasn't great. I was interested in most of the characters, though certainly not in love with them or even all that wrapped up in them. It was a decent plot, but each climax and problem encountered was such an identical replica of the preceeding ones that I ceased to be surprised after about two cycles of William's ruthless attacks or Waleran's cruel betrayals.
Two stars for me means "it was ok" and that exactly summarizes my feelings about it.
