I think Legacy is an audiovisual masterpiece, the epitome of effective style over substance, Kosinski's visuals and D'Punk's score making for the perfect marriage of components that overcome wobbly acting and terrible CG characters (although double Bridges is most welcome, convincing in both the Obi and Vader roles). The idea of bridging The Grid and the Real World by bringing characters back through was the logical progression, and I wanted to see what was next for Tron himself, as well as Cillian Murphy's underdeveloped real-world villain (hoping too that there would still be room for the progenitor in all of this, despite the outcome of Legacy).
None of this news, however, inspires me. Replacing Kosinski is a mistake, but a newbie (at least to blockbuster budgets) director could always have a mandate to follow Kosinski's style, which could have mixed bag results but has half a chance of success, particularly if Punk are back in the music seat (I thought they were?).
However Leto is single-handedly all the nails in the coffin at once. A self-proclaimed method actor, after his abysmal turn as gangsta' Joker, I can only hope that he goes full method and tries to insert himself into The Grid, and gets suitably de-rezzed for his troubles.
And if all this weren't the worst news in the world, coupling this news with the earlier announcement about Disney's abolition of physical media for catalogue titles, and what could have been the silver lining - a Tron 3 spurring Disney to release Tron 2 in 4K, which would have been stunning on the format - turns into salt in the already infected wound: no matter how good Tron 3 does, we won't get Tron Legacy in 4K.
Does anybody at Disney still have a brain, or are they just scrambling to avoid the iceberg they already hit back in March?
