In theory, I find there is no reason a trek movie cannot make 'marvel money' or be a hit and very successful...but if you are stuck thinking that a movie should be specifically made for old fans only then yeah, it won't be a big success. You are declaring failure without even trying. I don't see that being a great advice, tbh. Pegg, even after his own experience with beyond, seems to still not get it and he lives in the same alternate reality some old fans live into.
I think modern trek writers should be encouraged to make products that can reach a wider audience. There are no ifs or maybes here. The fact you have people who didn't like tos but they loved JJ's movies and are now watching current TV trek is a success, IMO. Isn't that, ultimately, the goal?
And let's not be disingenuos here, even if paramount&Co are realistic enough to know their movies cannot make billions they still, obvioustly, wish to have a successful franchise that can make the numbers their other movies don't make. Or they just have no reason to continue making trek movies. They wouldn't need that, if those movies were default made with the idea of getting the selective, limited attention of a niche audience only.
I always sense this subtext that trek fans are somehow more intellectual, or they appreciate and like quality writing more than the general audience and thus those who make marvel movies successful. I'm not a big fan of marvel movies but I'm not here for default overinflating trek fans that way, especially not when I read what some trek fans say online and what are their real 'issues' with modern trek.
As for Hawley, he already said he wants new characters and his movie doesn't want to be a sequel. He isn't interested about that. If rumors are true that the studio is pushing him to make a movie with this cast, I hope he walks away. If the next movie is a sequel, it should be made by someone who is truly inspired to make something with this trek. It should be someone who watched the trilogy and liked it and its cast..or it's just pointless to even try. Forcing a guy to turn his own reboot into a sequel screams disaster for me. In the end, neither side would truly get what they want. There are many directors and writers out there.
However, I still consider the possibility Hawley is considered for a spin off (that could be a tv one too) but sites are mixing things up and assuming if there is a fourth movie with this cast, it's made by him.
