I agree with the dumb decisions too. I don't get why they would all split up like that. The best fighters out of Alexandria at once isn't a good plan. Neither is focussing on saving Maggie to the detriment of everyone else. But I think that's what happens when you think/act with your heart and not your head.
His taking on Negan I didn't mind so much. They needed food and I'm sure Rick - and his ego! - was thinking "we've beaten everyone else. We took down the governor. How hard could it be" and has now paid for it. Plus, I don't think hilltop knew the numbers. They'd only been to an outpost and didn't know it wasn't the compound.
But I agree it is getting a bit formulaic. And the baddies get badder. But I guess that's also society. I just hope Rick doesn't become the biggest bad of them all. He's getting more hardcore each season.
Going to be interesting. He's down now, but I don't think it will last long.
Also going to be interesting to see if they can contain leaks so we don't find out who was killed before season 7's premiere. I think they start filming in June-July for the October start?? Going to be plenty of people trying to get photos of which cast members are still around.
