Interesting is safe, mild, and often ambiguous — in some contexts it's genuine praise, and in others it's the diplomatic word people use when they don't want to say "boring" or "confusing." That ambiguity makes it a weak choice when you actually want to say a presentation, story, or pitch held the room.
What "interesting" doesn't tell you
"The client found the pitch interesting."
Interesting as in engaged and impressed, or interesting as in polite silence while they figured out how to say no? "Interesting" doesn't commit either way.
What "captivating" adds
Captivating means attention was fully and continuously held — no ambiguity, no polite hedge. It's a strong, unmistakably positive claim about engagement.
