I tried to give this Pokémon rip-off a chance, but watching this series reminds me very much of when 4Kids used to dub anime. The theme song and the other songs in this anime are very reminiscent of the awful theme songs 4Kids would write for their anime (see "One Piece" theme song).
As great of a voice acting talent as Johnny Yong Bosch is, he's horribly miscast as Nate. His voice is too mature-sounding for 10-year-old Nate. Oddly while it worked for Nobi in Doraemon, it just doesn't work here.
The writing here is "typical children's show" writing...as in it's pretty mediocre. Adults will find the writing to be very juvenile and children will find it to be dull due to how "Japanese" the show feels. Perhaps this is why the franchise is not taking off very well in America.
Overall, you won't find this anime interesting. May I recommend something like the "Pokémon" anime or (if you're looking for something more mature) "FLCL" or "One Punch Man."
