Taking of Mount Weather
So you are waiting outside the main entrance with 1200 people. And the important task of taking out the turbines is done with only 2 people? There are dozens of entrances which they could have blown up quite easily, like the one Bellamy opened to let Clarke and Octavia in.
Those 1200 men don't see the enemy shooters getting out and open fire just at the moment the door is going to be opened.
Meanwhile the old president is locked up in a prison with no toilet, same as all the grounder sit in cages with apparently no need to pee or *beep*
Bellamy wonders around the building for days, even bringing the old president dinner and being in a arresting squad. nobody notices he was an outsider? come on...
These are just a few examples. I don't need the show to be fully logical en believable but it's getting a bit too ridiculous.
