I would stick to Nostalgia channel on YouTube as it's much more simple but a hundred times better. This is the typical example of "less is more". On Mundo Mistério you see a huge (HUGE!) effort to make something amazing that is actually just "meh" and very confusing at times. The acting is very poor, specially by the guy that plays Betinho whose character is totally unnecessary and makes everything very silly and childish. The special effects, animations and sound effects are amazing and what actually saves the series. I'm a huge fan of Felipe Castanhari but Mundo Mistério is his first project that disappointed me. A second season is well deserved but there's a lot to be considered and improved. Then again "less is more".
