Really surprised (though not shocked, I suppose) by all the negativity in this thread. Speaking as a life-long Trek fan, I thought Star Trek 09 was fantastic (easily many times superior to any of the Next Gen-era films), and much more harmonious with the spirit of TOS than many Trek fans are willing to admit.
Besides, with the Star Wars franchise in tatters in the wake of the PT and related media, I can't say I've been holding my breath for a decent ST. Ever since the announcement of Ep. 7-9, I've been groaning, "not again!" Even with competent people like Arndt and Abrams at the helm, I'm not expecting anything spectacular out of these new films. The Star Wars legacy has already been so irreparably damaged, it's hard to see how things could get any worse than they already are, or how anyone could even begin to repair the damage already inflicted.
That being said, in my judgment the selection of Abrams as a director is a big positive. He's an adept, versatile director who's already demonstrated a competence for both character development (which was almost completely absent in the PT) and the Sci-Fi genre in general. Ep. 7 will still probably be an unworthy successor to the OT--chances are slim that it will avoid imbibing at least some of the pollution of the post-97 Star Wars franchise--but at least with Abrams heading things up it probably won't be a major crap-fest like Ep. 1-3.
How is that a bad thing?
