I'm only setting my vote to 10/10 so that this show can have a better score that just a 3. In my honest opinion it's a 5.5.
I think that the show stays true to the humor that the movie had and the style is rather charming! The writing isn't the greatest sometimes but in other times it can be pretty alright. It's not a great show but it definitely doesn't deserve a 3.0. It is a bit odd that they didn't recast the original voice actors but the ones they have now are passable. Then there is the continuity error with the movies that Sam lives in Swallow Falls, while in the movies she only just came there. I can't recall it entirely but I remember Flint saying that he would erase Sam's memory if she ever moved.
This review isn't the greatest, but the show just needs some more recognition.
