I agree it is predictable of course jane had the vial and of course the unpurified one worked etc. But i like that about strike back from season 2-5 it has been like that alot not always but alot just shut your brain off and enjoy fun. There are still twists and surprises like character deaths to keep you on your toes though making it more fun (like me thinking maybe they do kill reynolds and loving it when it saved her)
Fair enough to me every season after season 1 (john porter and rick grimes) has just been following the formula season 1 set up but it doesnt matter to me this is not a "deep" show for the most part. I know im in the minority but i didnt enjoy season 1 very much.. too boring (good, deep etc but not fun) but i sat through because i knew how season 2-5 were gonna be.. that cinemax made them change it. That said i can recognize how season one was a "good" show. Just not entertaining enough in my opinion.
Then there are shows like westworld, american gods, the deuce, the expanse, fargo, banshee, black sails.. and many more that mastered being both "good" and entertaining. For me entertaining is first then if it is deep, original etc great even better.
To each his own though i used to watch alot of cop shows and thought they were good but now i have seen so much i fucking hate them sooo boring and cliche and almost all are garbage.. rewaching some stuff i used to watch i cant believe i liked it. Same with military dramas after watching seasons 2-5 of this most of them bore me compared to this. That is why i guess im biased when it comes to this i wanna love it so i do lol
