The clearing of the walkers was just stupid. Instead of simply stabbing them through the bars, in complete safety, they instead open the door ao they can be overwhelmed.
And the whole "secret weapon"...just makes no sense at all.
I didn't see why the first group didn't just partially open the door, stab then as they tried to crawl out then drag them out of the way to stab the next bunch. The walkers also seemed to have superhuman strength where they could grab a standing adult by the ankle and drag them into the room to eat them.
That "secret weapon" scene was Virginia's stupid way of testing to see who had leadership skills.
Finally we're supposed to believe that Morgan is going to take Virginia out by walking around with his stick and leaving threatening messages. It really has jumped the shark.
The really sad thing is that it looks like a Fellini masterpiece compared to World Beyond.
