Astro is to blame the most here, although I saw a few more recommendations scattered around too. But somehow nobody mentioned just how ugly the characters were and how poor the voicework. The color key is very good, but that's about the only good thing about the whole affair.

Abandoning with extreme prejustice.

UPDATE: By a coincidence, my posting crossed with Astro's post where he discussed ef: "I think the Sola connection is based solely on the pointiness of the chins, and nothing else." But then he illustrated the point with a flash video where the character looked miles ahead of Sola's (but yes, motions were unnaturally sharp).

UPDATE: Found old links which added to Astro's in persuasion: Hop Step Jump [link], Hontoni Taihen Desu [link] (this one is spoileristic). I'm glad it worked at least for someone...
