Why is Odysseus important in The Odyssey?

Odysseus is important in The Odyssey because he is the main character. In Homer's version of The Odyssey, Odysseus is portrayed as a heroic, great, powerful, loyal person. When, from personal experience in reading the book, he is not exactly the best person ever: There is countless times in which he cheats on his wife. Although it does not specifically state this; beneath the script you will find it clear as day. Then again being away from your wife for that long. Yep, i think i would cheat too. Loyalty's no fun. :)
