My son recently began using sentences such as " I am wanting to see that movie" or "Are you needing this?" Is this improper use of a present participle? Is this proper grammar? It sounds wrong to me, but my wife says it is fine.
Most of the time, we don't use these verbs in the progressive form, and in these examples I would agree with you that 'I want' or 'do you need' would fit better.
