Thinking about it, maybe with the Marvel deal in the back burner and some negative feelings of the test screenings made FOX realize "i think our efforts into trying to make this a more cheap, rushed out product aren't going to work so we should probably retool this for maximum profit and attention." Especially since nowadays, movies kind of live on having to be generally enjoyed by both critics AND audiences and aren't going to pass by on name recognition or solid word of mouth from just one facet. Thus things are probably tested more for how they'll do with both factions and to be honest the original production of New Mutants did feel rather rushed as it was a movie who filmed far later then any of the 2018 super hero films but finished before a lot of them. I have a feeling the 10 month gap is going to be going in and probably redoing a huge portion of the movie to make it scarier and flashing a whole lot more money then was probably used before. Since at this point, Marvel Disney has won the super hero game. DC admitted they're going to push forward with they're own thing and Disney just bought out most of the rest of they're compettition so yeah name of the game here is quality products you can sell to the most people. So if this can be remade to sell better then I'm sure that's what the team is doing.
Cool. That means I can see it in the theater. I only watch R-rated movies on TV as the gore on the big screen is really upsetting to me. I'll have to hear more about how scary it is before I make a final decision.
I'm guessing they don't want to put forth the idea there are major reshoots being done due to the huge negative backlash of films like Suicide Squad and Justice League that also went through heavy reshoots and severe re-editing after they're initial filming. Since yeah all major movies have reshoots but usually just pick up shots or to add a scene or two that may be needed for the final film (heck part of me for instance thinks the Deadpool 2 reshoots are to add in more topical humor to that movie. I mean they obviously did that with the Deadpool Meet trailer to add in jokes with Toy Story now that FOX is under Disney and Justice League's trouble so not like they aren't above making fun of that sort of current thing) but obviously a lot of backlash and sour perception really hurt those DCEU films which FOX wouldn't want for New Mutants. Again I am hoping though they are doing reshoots in some form to pump up the horror and darker imagery of New Mutants since yeah you do need time in post production but... you don't just delay a movie 10 months just for something like that so hope there is more to it they just don't feel like telling.
