Another of my favorite shows (although it has gotten worse over time) is 24. It is attention grabbing, action packed, and full of suprises. One aspect that never changes, however, is that there is a bit of a lack in adversity. I'll admit there was a little, for example they had David Palmer as the first black president, but for the most part, there were white members of CTU with white field members, and there were terrorists who just happen to all be Middle Eastern (with a few exceptions). You would think, with a rising hispanic population, that there would be a lot of hispanic actors working on the show, but there have been few to none (at least that I can remember).
I am a bit confused why Prison Break has a lot of diversity, while 24 has very little, and has an abundance of steriotypes, even though they are on the same network, Fox. Doesn't really make sense, does it?
