It´s not common today to find a really well rounded animated series, which makes sense and is able to capture even adult minds. 3Below is one of the rare cases, it´s so easy to watch the next episode, and the next, and the next....
The animation is very eye-friendly, rather simple but of high quality, with pleasing colors. Great voice acting, simple but strong story line with more than a few surprises. The characters are very well written, they have depth and are really relatable, even smaller side characters are often interesting (the blank bot "parents" are so much overblown, but at the same time really hillarious) and when something happens there is a real reason behind it. This show continues in the good tradition of Trollhunter, and for me it´s even better then it´s predecessor. A truly nice and entertaining piece to watch.
