It starts really well. You get attached immediately, you start admiring the direction work they did, environment, characters, everything... But it doesn't last so long. When it goes over the different seasons, the series starts to get some weirder villians, the script, the series itself demands it to be so, but they're so weird that you don't understand how they can appear; and it's not improving when it comes to their abilities: they seem imposing, but stupid and good-for-nothing when fighting.
