I've read some harsh opinions of this. Some of them have more to do with how things play out afterwards then with the event itself. I can' comment to that end, given that I've not yet finished the first book, but I found this to be a very powerful moment personally. Sure, you hate to see a fan favorite go, but everything has to go eventually, right? It's not as if we don't have all the past books and movies within which to relive our favorite Chewie moments.
I find the rift that has opened between Han and Anakin particularly emotional, being a father myself, I can't imagine what that sort of thing must feel like. But I think Salvatore takes a pretty good stab at it.
So, I look forward to the rest of this series. I've heard review that down it for being too dark. Good. Just the way I like it!
