Yeah, I ranted about this when I heard. I was pretty apalled. I said:
"WHAT THE BLOODY S**TF**K? Did today's date change to April 1st without anyone telling me?
OK, let's take a look at their reasoning:
1) Summers are better for "family tentpole" releases. Oh, so tell me, why wasn't that a problem for THE OTHER HARRY POTTER FILMS THAT CAME OUT IN NOVEMBER? Jesus f**king christ, do they really think this will increase their ticket sales? They're going to make a ton of money no matter when the film comes out!
2) "They are still feeling the aftereffects of the writers' strike and need the time to make sure the film reaches the widest audience possible." So does that mean that the script was rushed during the strike and sucks? BUT THE MOVIE'S ALREADY IN F**KING POST-PRODUCTION! FILMING WRAPPED! I understand that they really need to get their marketing team's s**t together, because we should have had a full-length trailer by now damnit, but the MARKETING team isn't impacted by the WRITER'S strike! They could still have cut together more trailers by now!
THIS DOESN'T MAKE ANY F**KING SENSE! I am ENRAGED."
And I still feel that way. BLEH.
