... damn, that's a bit strong isn't it?

Maybe? Some seem so  determinedly opposed to the family, when we know they have been,  and are  part of the character's whimsical development. 
We know they are part of Johns' and Franks relaunch which this  movie is mostly based on. 
Part of   Billy's main arc is gaining a Family. What ultimately helps define and   separates him from Teth Adam (his main villain (who also  lost his family) also given the power.  Yet Adam  is so lost he is unable to ever let go or share that  power. 
While what defines Billy is his ability to not only revert to a boy again, but  his ability to inadvertently share that same power. 
That is what the Wizard thought didn't exist. 
In doing so Billy gains a new family. Which as an orphan is what he wants. Probably the greatest (visual and thematic) way to express that in a superhero film is sharing that power. 
Potentially the most straight forward theme, of who he is. 
We also  know  the Adult versions have all  been cast. 
It's pretty blatant.  
So to be so determinedly opposed to 
that from the get-go, just seems like you might not  like where the film is distinctly  going.
 
	
		
	
	
		
		
			
	
		
	
	
		
		
			And  he's only sharing the power with them,  it does where off. (at first anyway, how they will play fully powered Mary and Freddy later on remains to be seen), but at first it wears off.
While they are all powered up to their idealized selves, they are mostly enhanced  by one attribute, when shared:
Billy - Power
Mary - Courage
Freddy - Stamina
Eugene - Wisdom (manifests as being able to control tech?)
Pedro - Strength
Darla - Speed
Only Billy has all the  powers / attributes combined.
		
		
	 
Didn't know that, ...
		
 
		
	 
Yes, going by Johns and Frank.
Although obviously Mary, Freddy, and the lieutenant Marvels existed before.
Johns just updated Tall Billy, Hill Billy, and Fat Billy into  Darla, Eugene, and Pedro.
But yes, only  Billy has all the  powers/attributes combined.
As to how sharing the power will be reflected in the film, that's what's being discussed.
In the comic it did wear off, and Billy ultimately faces the main villain (which was Adam) alone.
