[Eomer of the Rohirrim]

I have just read the Silmarillion for the first time and think its fantastic. Before I read it I had seen a lot of quotes and posts related to the book and from it I was able to gauge a few of the important characters. The name of Feanor comes up more often than most. I started reading the Silmarillion thinking that Feanor was this really awesome guy, a total hero, and ended up thinking that he's the most overrated character in Tolkien's books I've yet come across.
Can anyone argue the case for Feanor? I could be swayed rather easily but we'll see.
