Finally! A good six weeks after setting out on this project, I finally completed Kate Elliott's enormous Crown of Stars series. Seven volumes, over 5,500 pages and a fairly complicated storyline later, I feel like I've run a marathon. Sometimes it was an easy task and sometimes a gruelling one, but overall I feel this series has enough positive aspects to make reading it a worthwhile endeavour.
Overall, I would say that the Crown of Stars series is needlessly overlong and could have handled having a couple of volumes shaved off from it. It also suffers from the occasional bland turn of phrase, and the characters do seem to engage in a lot of repetitive getting captured, escaping, getting captured again stories, which occasionally has the disconcerting effect of making the reader think he's watching a late 1970s episode of Doctor Who.
On the other hand, I would also say that Crown of Stars features some excellent worldbuilding. Elliott has researched the historical period very well and, for everything she has changed, she's left enough alone that the series actually becomes mildly educational (her realistic use of the hierarchy of medieval power is very satisfying). Many of the characters are intriguing and their storylines worth persevering with (namely Alain and Stronghand), whilst others are a bit flat and tedious (Liath's, mainly).
Among epic fantasy series, there are certainly far worse available, but also ones that are far better. If you are looking for an already-completed, entertaining epic fantasy series, then Crown of Stars is worth a look.
