SKYFALL is the best Bond movie in ages. It has a smart script, great direction, and outstanding technical work from everyone involved. It is definitely the best-sounding Bond movie, period. Nice work by Per Hallberg, Karen Baker, Scott Millan and Greg Russell. The score by Thomas Newman was great too.
The best part for me was the fact that the movie went where the previous ones avoided; Bond's personal past before he was in the service. It is not explained in detail, but we get enough of a peek that we are interested in seeing where the future films will go. The script was a lot more complex than most action films for this reason.
