As a zombie show, I generally don't mind the unrealistic elements of the show. But this last episode really bugged me. As other's have mentioned, the Governor standing out in the open and sporadically shooting his machine gun in the air as bullets are striking the car next to him was just plain stupid. He was a sitting duck that any of the group with scoped rifles could easily have picked off. Martinez (or whatever his name is) was also standing out in the open without any cover seemingly less than 100 feet from Rick and should have been easily shot by Rick.
How the hell did a guy get up in the tower? Those towers are within the fenced off area. It's not impossible that somebody could have snuck through the fence and up to the tower in broad daylight, but it's really hard to believe. Speaking of the dude in the tower, he should have been able to pick off everyone in Rick's group like sitting ducks from the tower.
A dead body is not a shield to rifle bullets. Every single round that struck the dead inmate's body would have gone right through that body like butter.
Rick's whole delusional seeing things / hearing things is a horrible arc in the story and not believable. Speaking of Rick, by lucky circumstance he was unexpectantly outside of the prison fence when the surprise attack started. That put him in an extraordinarily lucky tactical position where he could have surprise attacked the Governor and his men on their flank. There's no freaking way that the Governor or his men could have known that Rick was walking around in the woods outside of the fence when they started the attack. Somehow, though, Martinez was right there ready to shoot at him.
I don't get the whole Glenn / Maggie fight going on right now. Who is mad at who and why? Am I to seriously believe that Maggie is balled up in the fetal position on a cot in a prison cell because some guy made her take her shirt off? After all the **** that is going on in the Walking Dead world, she's bothered by the fact that some random dude saw her half naked?
The whole deal with Glenn being gone for the entire attack and then driving back in at the end was weird. Is the prison like 5 miles around where it took him 10 minutes to drive from one side to the other? Once again was a great opportunity where he had the element of surprise on his side when the attack began. He could have easily surprised the Governor from behind during the attack and taken him out.
The attack by the Governor made no sense either. First, you'd think he would have attacked at night. Second, how effective is dumping off a truck-load of zombies? As we've seen, zombies are pretty easy to kill. So the Governor goes to the prison in broad daylight, kills one person, loses one person, and dumps off a bunch of zombies that will be easily disposed of, and then leaves? Doesn't make sense. All he's doing is inviting a counter attack on his town, which will do nothing but encourage the citizens in the town to want to leave even more.
