Has anyone seen The Wrestler? What are your thoughts?

I am amazed of how much critics love this movie. Yes, it delivers some great performances from its casts, most notably of course Mickey Rourke, but I thought it is also overrated. It's about an aging wrestler who try to get his groove back by going back to the stage, it's quite common to every sports movie. many sports movie are better than tis, Friday Night Lights for example
