Logos was fun.
The kiss itself was pretty lame but the scene leading to it was damn cute.
I had a lot of fun with the series, had a cool concept a decent story and nice characters, aside for the 2 not very good OP the OST was pretty good, the combat music was amazing.
I know it all comes down to subjective tastes. But I hated the character designs. They barely looked like people. And I much preferred Genesis mecha designs, though I did like the concept, an ideas behind the Logos designs. And the texturing really, really hurt Logos mecha. They seemed like glossy toys.
