Thor: The Dark World (2013) – IMDb. This was a good movie – good action and well written. The characters were good as well as the sci-fi/fx/cgi/etc.
While the overall concept is simple – bad guys want to destroy/rule everything and we have to stop them – I liked that it was also somewhat complex w/ the various character plots and dynamics.
The various characters all had their own subplots and it all added up to a less-than-simple solution to the various problems. Good stuff.
