Season one was awesome and absolute adaptation of E.T and X-Files ,It and some classic stuff.Season 2 was exciting and ok.but season 3 was so so brilliant.and has remained me terminator, The Thing and some classic references.Just don't judge the show and watch it .even a second I didn't get bored.and mind-blowing.some r saying comedy is ruined but I say it's a correction of season 2 which is dark and get bored sometimes.but this season comedy has really worked really well.yes there are some comedy that didn't workout in episode but it's not a mistake.actually well returned well structured writing ,CG work just out of the world,artwork cinematography was awesome, background score really so good as usual.I would say it's only series which is re-watchable again and again.please make season 4 as well like this.
