- Incorrect: 'The movie disillusioned me.' (unless it destroyed a specific belief about filmmaking).
- Correct: 'Working there disillusioned me about the industry's values.'

FAQ
Frequently Asked Questions
Yes, it describes a negative process and outcome—the destruction of a positive illusion, leading to disappointment or cynicism.
Yes, but it's less common than the noun 'disillusionment'. 'Disillusion' as a noun means the state of being disillusioned.
'Disappoint' is broader and milder—it means to fail to meet expectations. 'Disillusion' is stronger and more specific: it means to strip away a false, often idealistic, belief, causing a more profound loss of faith.
Both are correct and often interchangeable. 'Disillusioned with' often focuses on the topic/object of lost faith (with politics). 'Disillusioned by' often focuses on the agent/cause of the disillusionment (by a scandal).
