What do you think of the Homunculus of the first series of FMA?

I think that the original FMA and the manga portray the seven deadly sins in (though different) equally interesting ways. Though brotherhood neglects to develop their homunculus characters as much (except for greed, he gets character development). But that is a common theme in the differences between the series. Brotherhood is a shonen and develops its plot, while the first anime focuses on characters. Brotherhood is supposed to be a carbon copy of the manga, which I liked a lot because it covers a lot of things that the first anime doesn't in terms of character relations and ishbal flashbacks. But if you chalk it all up, both seem to cover relationships in almost the same way ( a little negligent on the PDA). Other things that bond the first anime and the manga/brotherhood are their themes, which are well presented to their audiences, though in different ways.
