In my opinion everything contributes to why I'm addicted to the show. I upendo the humor (Tony's film sayings, how he talks about girls, his reactions to certain things, Ziva's mess-ups, etc). I upendo the relationships, and not just the romantic ones... the relationship they have is so strong and it makes me want to be a part of a bond like that. I upendo all the characters, with the exception of Vance... I'm not crazy about him. This onyesha has everything; drama, emotion, raw passion, sadness, happiness, excitement, etc.
I do upendo the romances e.g Tiva, McAbby, Jibbs but I upendo the comedy side of it as well, it makes it different to other crime shows out there. I think Tony is absolutely hilarious especially when he is with Ziva au McGee. I just upendo everything about the onyesha really :)
I cannot pick just one. They are all what makes the onyesha what it is. It is the mix of romance, comedy, action, and sad scenes. With that, they bring to the table, what other competing shows cannot!
