Not doomed certainly, problem with Race 3 other than being rushed was that first, he used it as a launch device rather than a genuine movie. Secondly, the idea of Race 3 with Salman was misfit, Race was always more suspense & thriller franchise rather than the poor action movie they tried to make. Saif in Race 3 would've been made with lower budget and would've suited the theme of Race movies with the style of Saif's character.
And what to say about the director, as i said, launch device.
And then obviously being rushed.
Now coming to Eid project, it'll be rushed, mostly will have another not so good director and supporting cast might be 50/50, could be good or could be yet another launch device. And obviously rushed.
Not completely doomed, but chances are high. I mean it's not compulsory to come on Eid, yeah, the fans want it but as the great Ian Malcolm once said "Your scientists were so preoccupied in whether or not they could, they didn't stopped to think if they should".
