What?! You mean their insurance division shouldn't be making games too?
It's funny, since 2000, people have been asking why they aren't working together as a company to promote their games. People asked why weren't they making movies and shows for their games?
Now that they are wisely working together to promote different divisions, we have people complaining.
Ultimately, it's good for gamers. If these endeavors are successful it means more games in the franchises we enjoy.
I would love if we still had games like Arc The Lad, Legend of Dragoon, Killzone, Alundra, Dark Cloud, but the games weren't successful enough on their own. Ironically Arc The Lad did have an anime adaptation. It wasn't very big budget and was kind of lost in the sauce. It doesn't help that it didn't get a big push in the West. Transmedia means we get a better chance of keeping the franchises we like and getting new and interesting IP.
You'll never make everybody happy though.
You could have done a 1:1 movie with the original actors who are now in their late 30s and early 40s. You could have done a 1:1 movie with new actors, or you could have done a new plot with new actors. If they had done any of these, you'd have people complaining. Ultimately, they picked the one that has most long term potential for more games and more movies.
