Why did the critics not like about this movie?

I Liebe this movie, and if your a member of this group then I assume Du are too. But however alot of people did not like this movie and it got terrible reviews. What I dont get is why??? At first I thought maybe it wasnt anything like the comic books, but then I did some research and found out that in the comic Bücher Elektra was a bitter and angry assassin with psyche powers, JUST LIKE THE MOVIE! So I dont know what there problem is...
