Didn't really like it but I wonder beside brand name why use Wednesday Addams?

It would work much better as a new character, because this is not Wednesday or the Addams family for that matter, at the heart the Addams were always about familiy and while they had a weird lifestyle they were all good at heart, Wednesday is cruel not only strangers but also her parents and even Thing one of best friends.

Of course Wednesday is not a real person so she varies from adaptation to adaptation, but she is just really unpleasant and boring, using a lot of time for some forced drama of what she is not, its just boring.
