December is one of my favorite months as it's Christmas time, and the end of the "old" year. I had a good December personally as well.
Favorite TV Show: Orange is the New Black
My wife and I started watching Orange is the New Black again, this time the 2nd season. This season takes a more serious turn, but still has its more comedic moments. I wouldn't stay it was as good as the first season, but we're looking forward to starting the third soon enough.
Favorite Video Game: The Legend of Zelda: A Link Between Worlds
The Legend of Zelda series rarely disappoints, and the new adventure just for 3DS (and a sequel to the SNES A Link to the Past) still shows that Nintendo still has their old magic. It was better than a lot of modern Zeldas which are often too easy and a little unoriginal. The wall merging is neat, and the dungeons are creative.
Favorite Film: Star Wars: The Force Awakens
This one I figured would eventually be my favorite film of December. The first episode of the sequel trilogy did very well with critics (and much better than any of the prequels), but some fans thought it was "just like" A New Hope. There are similarities sure, but I thought it was original enough. The only thing I didn't like is that it left a lot of unanswered questions that leave you wanting to see the sequel as soon as possible.
