I LOVE DISSENT PLEASE TELL ME WHY!!!
I'm just not taken by him the way I was in the comics when he took this form. From just this trailer (I'm not judging the entirety of the film) it looks like too much of a good thing. It screams, toy sales, and merchandising in the most blantant way, and in turn doesn't come off as genuine. I know that he was only left this way to play to the children; this coming from someone, who in the past, has defended the use of a Jar Jar.
I want to be wrong about this, and I probably am, but that trailer did nothing to sell me a movie, and everything to sell me a funko pop.
Now, on the other hand, I agree with Jev, and believe that Drax will steal every scene he's in. It is literally just Baby Groot that I am not smitten with.
