My thoughts on Disturbing Behavior...
1) For whatever reason, this seemed like a made-for-TV movie, and not an actual motion picture. But still, that doesn't mean it's not enjoyable to watch.
2) When Steve took away Gavin's gun, that turned out to be a huge mistake. On some terms, I would say that Gavin's brainwashing transition was all his fault. Maybe things would've turned out differently if Gavin would've had that gun. Just sayin...
3) What I didn't understand was, if all the trendy high school students were brainwashed with some sort of implant technology, did the corrupt school staff ever consider what would happen to these students when they grow up and get out of high school? Did they ever take technical malfunctions into consideration? I mean, the brainwashing process seemed to only focus on making teenagers participate in school activities and group-think. But what about when high school is over? What then? The mind control project seemed overlook a lot of important details.
4) Another thing I didn't understand...were the implants designed to prevent the students from having sexual impulses or something? How exactly were they supposed to become normal members of society? Better yet, seeing that the brainwashed students were so 'pure' and all, and yet weren't capable of having sex...how exactly were they expected to start a family in the future? And also, every time they did have a sexual impulsive or desire, their mind would switch over to violence and murder. How exactly was that supposed to work out in the long-run? Yet again, more flaws in the mind control project.
5) What was up with Steve's dad?! Seriously?! That dude had like no personality at all.
