Dramatic chipmunks are dramatic.

In response to the first question, Othello is dramatic. Iago's attempt to break up Othello's marriage to Desdemona is an exaggerated response to his jealousy, but it could happen. That kind of thing does happen. The fact that it's absurd is what makes it a story worth telling.

Certain parts are less realistic, such as the asides. "O, you are well tuned now!/ But I'll set the pegs that make this music/ As honest as I am." II.i.199-201 I know that's just a literary technique, and it conveys the thoughts of the character, but... I don't like it. It feels like the author took the easy way out. Surely there's a way to slip that information/impression into another conversation or something.

That's true of all plays, though. Othello in general seems to be pretty realistic for a play. There are no hippogriffs or anything like that. It all could happen. It just usually doesn't, which is good, because I hear this is a tragedy.
