The Midori no Hibi set included a promo DVD for Media Blasters and their Anime Works label (or is it "imprint"). It's always fun to pick on trailers.
Ironically, Midori no Hibi itself was there too, and honestly the trailer was so-so. I think it would not entice me to watch by itself. That's a serious loss for a trailer of underappreciated series.
I never had much interest in Oh My Goddess franchize, save for the Adventures of Mini-Goddess, but the visuals are so amazing that I'm wavering. On the other hand, it may be letterboxed. Might as well throw one into Netflix queue. Win for the trailer.
{Update: Steven e-mailed to tell me that: "The MB release of the first season of Ah! My Goddess! is not letterboxed. It's anamorphic. It's also a very high quality release in every way, as good as you can get from anyone else." See also: AMG Continuity.}
Berserk seems like a trash with swords (not necesserily is such, but we're talking the trailer). I even selected a flattering picture. Loss.
Phoenix is curious. The trailer presses on Tezuka heavily, and I disliked Astroboy. Can be anything, but at least it's teatrical animation level. Draw.
The trailer for Ramen Fighter Miki makes me regret missing the v.3, which now cannot be gotten except off eBay. Win.
The problem with the mecha powered by pure lesbian power is, I know about it, so I cannot tell if trailer would deceive me into trying it. I would say not, it's pretty honest. So, a loss.
GaoGaiGar almost made it, because I would really like to see some thing "old and good", like Patlabor. But 49 episodes? Also, the quotes from ANN et.al. irritated me immensely. Clearly a misrepresentation was going around. Trailer loses!
Iria - Zeiram, in contrast, seems ok. Looks too much like Blue Gender though. So I'd say a win, if weak. {Update in 2012: See a comprehensive review by John Sato.}
I also skipped a bunch of trailers, about a half actually, from which I could not get a compelling snapshot. Maybe I'm too picky?
QUICK UPDATE: Awww, I knew I was forgetting something: Genshiken. They had that nice pale girl with a mole. Draw for the trailer: no change in my inclination.
