Catching up on the thread here..
Arrival was great, movie of the year, nah, imo.
Place I go to to find out about upcoming movies, is slashfilm.com, they are great.
One site that I found, but reveals all spoilers of movie's endings is moviepooper.com. It also helps you understand some / or hear about other viewpoints of films endings. I found this helpful for some movies I didn't fully understand myself.
Saw Fist Fight last night, decent movie, some laughs.
