This is great, a masterpiece. Very emotional, interesting but also funny at the same time. There is a character for every kind of personality. Above all very addicting, you may lose control of yourself.
Klaus is a funny dude, who you eventually will like.
Elena is my favorite personally. Her character is very emotional, sensitive, weak, whiny but also very caring.
These are traits that " modern-day " forbid, yet I find it very appealing to her. Everyone falls for Elena for this reason, and of course how well Nina plays her, just as Katherine.
Caroline is extremely funny, she is a more straightforward character, along with Damon's show has lots of humor. This show is just way too good, I wish it was endless.
This is the show for couples would say, even married. Maybe lonely people will find a bit of sadness in it because the show is wrapped around love and sacrifice, being alone isn't exactly fitting with that.
