This was closed because of the 'misconception' that poignant carries negative connotations. I found it because I was going to ask something similar.
I didn't think it carried a negative connotation, but it does convey sadness and possibly regret.
Sadness isn't (by most standards) positive, and certainly regret isn't. The OP wanted something more positive. Poignant implies a strong feeling but I believe the OP meant, what's a strong feeling that doesn't carry a sad or regretful connotation? They just said 'negative' instead.
Have I missed something? Is the question, in that light, still off base or off-topic?
