season 2 taking on the demogorgon in the bus

made no damn sense. the kids knew it was a demogorgon. they saw that only eleven took it out and fire, bear traps and weapons did almost nothing. somehow assault weapons do... something sometimes nothing when the plot demands it.

so they are going to ambush it by facing it 1v1 with a nail bat.. Like had they had some intricate fire trap set up again sure. and I get they are kids. but this was beyond believable and dumb
