Everybody is different, some like comic cartoonish series, some comedic, some action etc. This series and this episode is exactly made for the kind of people who likes "serious drama", but wants constant excitement. It starts just like anything, but then, it puts the pressure on and on and on, and it's a rush of joy and tension watching it. As a pilot it could have been just a movie and i would have been more than happy, gladly we got more and i can say it's absolutely worth the watch, but the first episode really impress me.
Have to add this before i forgot to mention it. The script, the writting in this series is top notch. Sometimes after some dialog so well written, i had to stop and concluded that was very well written. It's nice to see well written shows for grownups.
