There are so many people on here complaining that this show isn't realistic. It's a TV drama, not a reality show! Way too many people with expectations on a realistic drama, when, let's all be honest, these shows are NEVER realistic. If you want reality, look elsewhere.
I personally found this show to be intriguing, and intense. The previews were awesome, and the show did not disappoint. I always find the pilot episodes to be chalked full of introductions, and sometimes find pilots to not be as strong as the following episodes that's really allow the stories to shine. I got just enough intrigue to catch me in, but not spoil too much.
Peter Krause is the obvious star of the show, with a strong character and a backstory I can't wait to see more of. Angela Bassett was equally strong in her role as an LAPD officer. She's one of the best actresses out there and I'm super excited to see her in this bad ass role! Connie Britton is also great, but I wanted to see more from her. The rookie fireman was the weakest part for me, but there's potential for an incredible character arc if played right.
I say ignore the other viewers who are expecting a reality show, and take this for what a TV show is supposed to be. An escape from reality.
