Not sure if this show just isn't for me but random thoughts:
A whole lot of shit the Jackal does makes no sense. He's billed as a guy that makes no mistakes, yet he does shit like openly discuss killing someone for money in public with a woman he literally just met 1 minute prior. He leaves a massive wake of destruction and obvious clues almost everywhere he goes. At times, he comes off as less of a master assassin than a more serious Mr. Bean type character who is just constantly at the mercy of an endless series of implausible accidents.
There are so many plot inconsistencies and unbelievable coincidences that it would take all day to go through them, and the plot is also extremely telegraphed almost all the time.
The tech conspiracy at the heart of the plot is insanely stupid and lacks any depth, especially compared to entirely realistic conspiracy in the novel. Complete waste of Charles Dance's talents casting him as basically a nameless, boring, corpo piece of shit that you forget exists every time he's off screen.
The cast consists of quite a few heavy hitters, all great actors in their own right, but the show still feels like a soap opera half the time, especially the family subplot. Everything to do with his wife, child, and in-laws is so incredibly cheesy, poorly acted and poorly written that it feels almost deliberately bad.
I know that real life intelligence agencies are exactly this evil and worse, but this portrayal of MI6 just feels generically cartoonish as hell. None of the characters involved are interesting at all.
Bianca's character makes no sense, other than being a generic avatar for MI6. There is no reason for her to have a family subplot at all, it was all stupid and unnecessary.
Nothing that happens carries any emotional weight at all because we just hop from one unbelievable scenario to another.
I thought the first few episodes were pretty good and then the show just entirely went off the rails and got goofier every episode. I will probably still watch the next season because I'm a glutton for punishment.
