The problem with endings

I just finished The Kite Runner, which is No. 1 on Book Sense's bestseller list. (Booksense.com is the web site of independent booksellers and a great place to get reading ideas. )
"The Kite Runner" is the story of an upper-class boy growing up in Afghanistan in the late 1960s and early 1970s. His mother is dead, his father is withholding, and his best friend is the servant's son.
The beginning of this book is amazing, startlingly strong, utterly gripping.
The middle part is interesting, very good.
The ending is bad, too many coincidences and loose ends coming together, almost over the top.
Don't you hate it when that happens? Where was the author's editor? All he needed to do was throttle back a little bit.
On the whole, though, the good outweighed the bad, because the good was so very good.
