A quality cartoon
9 April 2012 | by moonknight-4See all my reviews

To be honest , I never watched the original thundercats except for a couple of episodes . and I thought it was corny - and that silly idea wouldn't work nowdays . but I gave it a shot , and this remake not only topped all my expectations . it became one of my favorite animated shows of all time . (up there with TMNT (2003) The Jackie Chan adventures , and even Avatar : The last airbender . just to name some)

it's really in line with them in terms of quality and charm . not only that , but it even easily beats most of the real "anime" out there . and I think this combo of American writing and voice acting with Asian artstyle and animation is just proved as a great choice again .

So , lets break this show down :

Artstyle - some may disagree with me but as an artist myself I find it very beautiful , it's colorful and easy on the eye . but it's detailed enough to be taken seriously . the designs have a modern touch to them and fit the fantasy environment well . and the characters have a lot more ...well , character than the original ones - who looked like your cardboard superheroes.

Animation - every episode so far was animated without laziness , with fluid character movement in every degree possible . and amazing action scenes . the quality is as good as something you would expect from a movie . and I just hope the animators realize they put that as a standard for the show and will never get lazy .

Story - Although I'm yet sure to where this show is heading at , so far the plot lines were good . every episode was pretty epic , and even the fillers were pretty good (the main problem with most "anime") they dealed with serious conflicts . there was a good amount of character development , background stories , and relationships building . and the dialogue was believable - as in , they feel like real people that you can connect with . the only problem I can think of is that every episode is so packed with things that it's sometimes rushed , and has some "holes" in the sequence of things so it could fit into this short time .

Music - the music is fantastic , other than not having a theme song (which kinda sucks).

but thats no biggy at all , the show is entertaining to watch to both old and young and it saddens me how people who can't let go of their nostalgia give this excellent show a bad name and drive it to cancellation. I hope that it will live up to it's planned amount of episodes because I just can't wait to the next one - CN got themselves an addict :)
