The word sounds natural in everyday conversation.

When Not to Use “Fantastic”
“Fantastic” can be too informal for formal, academic, or professional contexts. It can also be too vague if you need to describe exactly why something is excellent.
Consider:
“The report was fantastic.”
This statement does not tell readers whether the report was well-researched, well-written, comprehensive, or simply pleasing.
A more precise sentence could be:
“The report was comprehensive and well-researched.”
Similarly, avoid using “fantastic” when you mean “very large” in formal contexts. Use “enormous”, “substantial”, or “considerable” instead.
