Michael Cudlitz ("Bull" from Band of Brothers) is going to be on next week's episode. Pilots are seldom anything close to the rest of a series. Different writers, directors, ect., will change the look and storyline. I'll give it a few more before pulling the plug.
Considering this is the first TV series to depict soldiers while we are at war with the enemy since Gomer Pyle USMC, I think they've made a good start.
