I was more excited when I heard B.D. Wong was returning. Nonetheless, a lot of people were endlessly moaning disappointed that Malcolm did not appear in Jurassic World. Therefore, I think it is a good strategic move by the film makers to make Malcolm appear in this film. Maybe this time, the fans will shut the hell up be content about the cast.
Personally, I will probably only enjoy JW2-Malcolm if he stops behaving like a standard action movie hero, and will be a bit more like an actual mathematician as portrayed in the novels.
