I would have to pick Sci-Fi and Fantasy. In my Top 10 of movies is Terminator trilogy, Lord of the Rings trilogy, all the Star Wars movies and Matrix trilogy. However, I also like the GodFather trilogy which is Drama, along with GoodFellas. Also in my Top 10 is Office Space (comedy) and Fight Club (thriller?). However, I'll pick Sci Fi and Fantasy as I enjoy the SpiderMan flicks, Excalibur and others.
I said Anime & animation (without the anime part). although most of my favorites are not of that genre, this is the only genre in which I like almost all movies. All of the Disneys, especially.
My other favorites are just scattered around the different genres. Some thrillers, some Sci Fi, some Drama. Some I don't even know where to place.
I chose Comedy because that can incorporate my other favorites. I absolutely adore musicals and I am all about animation movies. I enjoy drama and sci-fi as well, but I have to be in the mood for something more serious. I usually prefer something that's going to make me happy.
I will also go for a good comedy. My favorite movies are not funny but when it comes to see a movie, a comedy is the only thing I can digest regardless of my mood or situation.
I chose action and adventure. I did this considering both movies and TV.
On TV, I have come to really enjoy the more thoughtful crime dramas, such as Law and Order: SVU and CSI over the action shows. The action shows have become very bland.
In movies, though, I prefer action and adventure, as a genre.
My favorite genre is science fiction / horror. I really enjoyed Aliens (although I found Aliens 3 & 4 to be a disappointment. I also liked the first Predator and the first Resident Evil. I just saw Resident Evil 2 last night and gave it a a B- or a C.
