Surprised nobody's commented on Day 7 yet, so I guess I'll start! Spoilers below:
What a great opening!
I was quick to groan when I heard Tony was brought back from the dead but I'm actually glad to see it last night, looks really sinister, although I still think he's undercover somehow. Was good that not only was he introduced at the very beginning rather than dragging it out, but Jack asked the same questions the fans would have as well, so at least the possibility of him as an undercover agent has been brought up already. Also good, Jack's run-jump-roll-tackle on Tony, Jack giving a shifty look at the FBI female agent after saying 'DAMMIT!'
like he's thinking "That's my line!" , a plot that isn't a 'which terrorist group has the biggest WMD this time' and the new clean blue sepia that covers the screen rather than the orange, almost darkish one from past seasons. Obviously due to a change in location but it does make the series seem somewhat fresh. Looks good too.
Welcome back Jack. After a year and a half I can say it's good to see you again! But here's hoping the rest of the season goes as well. I remember Day 6 starting well but going downhill since.
