What brings it down is the fact that the main characters cannot lose even once or the story will be over. All tension has been thrown out the window. We know the main characters are gonna win, and so do they. What irks me about this is that it's telling the audience that the show is meant to be brainless entertainment, yet it's a story centered around games, wit and intelligence. I am not sure if this is idiotic or secretly genius.
The one thing keeping you watching is the question of HOW they will beat their opponents, and if the show does one thing right it is the bombastic presentation of their victories. The journey there can however be improved significantly.
I do enjoy that our sibling protagonists are pro-active and that they actually enjoy being sucked into another world, setting them apart from the typical heroes that just want to live a normal life. Their comradery is cute and their relationship is thankfully kept platonic. I can't say they ever grow as characters through the story, and I doubt they will in any potential 2nd season.
Overall, it's a show with plenty of fun but with a shallow core.
