For the most part, I enjoyed LOTF. I thought the fall of one of the main characters was handled well, and especially liked the political machinations that character gets into. There is one thread within the series that I felt took too long to come to an end and I was somewhat disappointed by some of the actions (or non-actions) that the Jedi Order as a whole took. Overall, though, I did have a good time with LOTF. As for FOTJ, I haven't yet started it despite owning all of the books released so far because I'm currently working on getting caught up on the DS9 Relaunch, so I can't offer any thoughts there.
