As someone brought into comics with the New 52, Barry Allen is the first Flash that I've read on a consistent basis. However, I have just recently started Mark Waid's Wally run (about 30 issues or so in), and realized that The Flash from the Justice League cartoon was also Wally. I have never, and still really, don't see THAT much of a difference between the two (so far), and am very curious as to what makes someone a Barry or Wally fan. Have I just not read enough of either character? Is there something I'm missing?

So I figured maybe you guys could point out what I haven't seen yet. Sometimes, it just takes another pair of eyes to point out the obvious. What do you consider the major differences between Wally and Barry?
