PSYCHIC GETING KILLED CONFUSED ME THE MOST

WHEN I WATCHED THE MOVIE I WAS TOOKEN BY SURPRISE WHEN THE MOTHER SHOT THE PSYCHIC.IT MADE ME THINK AT FIRST SHE MAY HAVE BEEN CONNECTED WITH THE KILLER OR EVEN HELPING.BUT AS I'VE READ MORE REVIEWS MENTIONING EVENTS WERE'NT CONNECTED IT WAS PROBABLY ADDED IN AS A FILLER SCENE TO ADD MORE TIME TO THE FILM.I KNOW THIS WAS THE WAY THEY DID ALOT OF THOSE LOW-BUDGET FILMS FROM THE 70'S AND 80'S.THEY PROBABLY DID'NT HABE THE BUDGET PROPS TO CONNECT SCENES PROPERLY AND ADD FILLER SCENES WITH NO CONNECTION AT ALL TO SAVE BUDGET COSTS.
HARD TO TELL BUT THAT'S WHAT GAVE THESE MOVIES THEY'RE MYSTERIOUS AURA COMPARED TO BIGGER BUDGETED PROJECTS FROM THAT TIME PERIOD.
BY THE WAY I THOUGHT THE FINAL CHASE DID A GOOD JOB OF GRABBING YOU THROUGH THE THROAT AND KEEPING SUSPENSE AS IT WAS DRAWN OUT NOT JUST A FEW SECONDS COMPARED TO OTHER FILLER MATERIAL IN THE FILM.EVGEN WITH THE HEROINE BEING PARTWAY NAKED WHICH I'M SURE WAS PUT IN TO GIVE IT A CAMP FEEL.
