Just finished season 2. You would think after 5 years Ellie would lose the devil may care attitude but nope. So many bad decisions that the writers just pull out the trusty Deus Ex Machina to solve any problem.
It's obvious the WLF's are an actual army and yet 2 young women decide they can storm the castle, find one particular soldier and kill her. They saw where they killed about 20 of the Scars and didn't think that maybe this is a bad idea.
Then they hole up in a theater, find a generator and light it up without thinking one of the patrols might see an abandoned building with the lights on.
I was waiting for Ellie to fire up the amps in that theater and start shredding on the electric guitar but that never happened. So I guess that was one good decision amidst all the bad ones.
