In honour of today being Halloween, what do we all think is the spookiest, most spine-chilling episode of TNG? Will you go with Identity Crisis (which seriously creeped me out as a kid)? How about Schisms, with the sinister clicking aliens? Then there was Night Terrors. Maybe all three freaked you out, maybe none of them, or maybe a different episode holds the honour for you. For me, I think Schisms wins this one.
