It's a good British drama with strong start and weak finish.

I don't mind watching clichés, as long as they are done right. And this show has done it rightly so.

The premise and setup is amazing, opening scenes alone can put you on edge of your couch.

Transformation of the characters are done perfectly.

The only problem is it gets a weak ending. It's not the worse but couldn have been better.

If you have time go check it out, 'British service agents are lot more better than the US agents.'

Some bonus points , Keeler Hawes's hot , also Sophia Rundle is hot, even the dude Richard Madden is hot. So it's treat for everybody.
