if it is going to be successful then 3 things should happen.
1. release it on a date with no real competition.that means any big film,family or blockbuster.
no point releasing it on the same day as say 'national treasure 2' or 'another night in the museum'.
2.a top notch marketing campaign to rival 300.the trailer should be of the highest quality with different versions released at peak viewing times i.e sports games ad breaks,24 ad break.
3.the predalien should be handled with care like venom,godzilla and the hulk.give people glimpses but nothing else.
the adult rating will effect the box office revenue but taking everything into consideration it will make $20m topline.
it will only do more if it is critically recieved well. don't forget avp didn't have any pre release viewings to the critics,probably because they knew it was bobbins.a repeat of this would spell certain death for both franchises.
