For me, personally, the genre I enjoy most and which is by far my favorite genre is fantasy. The works in this genre are The Lord of the Rings by Tolkien, A Song of Ice and Fire by George Martin, The Dark Tower by Stephen King, etc. What I like about this genre, apart from all the fantastic creatures and magic, is definitely the heroism and strength of many characters, who go through many perils throughout their quest. And of course, there are dragons. :)
There are some downsides to it, of course. If you don't like unrealistic situations, this is definitely not for you. Characters may often be portrayed as either good or bad, and you know that in the end, good always wins, which is not always the most interesting ending.
A) Is not always directly stated.
Sometimes the main idea is implied instead of directly stated. You can also get the main idea from the Theme which is stated at the end of the first paragraph.
i hope i helped:)
