This is by far one of my favourite dramas to watch! The characters are all very entertaining, and the main plot is the most interesting one I've seen thus far (in a good way). All the acting seems very natural to me, and there is almost nothing wrong with the drama itself. The games themselves are all great, except maybe the night before the remaining members enter the Ultimate Space (that one was good, but I feel they could've made it a bit more interesting in some way or another).
