TSUKAME PURAAAIIDOOOO!
What Gilder says is mostly true. G Reco is written by Tomino, the original writer for Gundam, Zeta Double Zeta, and Turn A Gundam. Therefore it has this kiddish feelings, because he never ment for it to be written for adults. The series is very wishy washy and has a very happy feeling to it, even when characters die or feel sad. It differs from more serious series like the Alternative universes SEED, 00 or Wing in that regard.
If you are going to watch it, atleast go into it with a childlike mind, since thats the target audience Tomino wanted to fall in love with the show, like how people fell in love with the original gundam in 1979.
That said, are you watching Build Fighters Try, Gilder?
