.. but the very next, you gave your memory away ... or something along those lines. It doens't always have to fit the song or pun - so no pun intended. Just go with the flow. It is a massacre anyway ... well according to one of the titles of the movie. Of course as others also have noted: you could also go with "I know what you did last summer" ... just replacing summer with Easter.
The blueprint is there - but it makes you feel that the other movie is a citizen kane - compared to this. Try not to - this movie has no chance to withstand that comparison. You could also say that there are some notions of Scream in here ... again a comparison this movie would not survive - it would be a massacre to quote the movie again.
The costume is nice, I reckon the actors look good ... and the cinematography is really not that bad ...
