The characters just seem unbelievably stupid so you just can't believe they have survived as long as they have.
Like, they meet some crazy militant group with fanatical followers who threaten them. Their plan? Hand over every single one of their weapons and then look to find more to fight them ... and when they do find some they hand them over to another faction of the same group!
Sorry, they all deserved to die a long time ago. Except Maggie, she can come stay with me and I'll keep her safe. Oh yeah.
The last one we watched had the continuity jumping all over the place like the director fancied themselves as making something arty or "thinky" like 12 Monkeys but didn't quite have the skill to do so, it was choppy, confusing and we gave up.
It's hard to do when you have invested a lot in a programme but better not to waste more time on it. If it comes good you can always catch up but you'll never get back those wasted hours if not.
We've also given up on Westworld ... Anthony Hopkins gave series 1 some gravitas but the current one doesn't seem to be going anywhere. This happens a lot - people have a great idea for a show (I know that one is based on an old story) but then don't know how to explain "the mystery" hook or they want to turn it into a never ending soap opera instead of focusing on the story arch of the characters. That's why Game of Thrones is so good ... that and all the boobs obviously.
