Because the awareness is building and people are really pumped and hyped this year. Two major franchises are ending and closing out their chapters. Avengers and now X-men. Will Avengers get some more attention? Sure but not like a super huge amount as Audiences are carrying heavy expectations from a Simon Kinberg product because of just how many fans there are of X-men films and him as a filmmaker. Knowing it’s his last film with Fox before shifting to the MCU is really building audience interest and steam to see this movie and see what massive epic adventure he is meticulously crafting with great nourishment and dextrous critical expert care.
I think many are quite hyped to see the final X-men film under Fox and see how it will end and wrap up the various complex, mature ultra-grounded and adult-themed conflicts, story arcs, and character arcs
Don’t throw away audiences’ amped up desire to see a Simon Kinberg X-men film. Most are highly anticipating to see his directorial debut and see how technically polished and superbly crafted his script is. The brand name also helps with recognition but this will be almost secondary to Kinberg’s built in fan interest and following.
