✕Common Mistakes
C'est vraiment intéressante.
The adjective must agree with the subject. Use intéressante only if the noun you’re referring to is feminine (e.g., une idée).
Il est vraiment intéressant.
Il est is used when the noun is explicitly mentioned (e.g., Il est intéressant, le film). For a general statement about something just mentioned, C'est is preferred.
C'est très vraiment intéressant.
Stacking adverbs (très + vraiment) sounds redundant. Choose one intensifier.

That's very interesting.
C'est fascinant.

C'est captivant.
That's captivating.
Cultural Tip
In French, using vraiment adds a personal, enthusiastic touch, while très is more neutral. Be mindful of gender agreement: if you refer to a feminine noun (e.g., une idée), say C'est vraiment intéressante. Also, avoid overusing strong adjectives in formal writing; a simple C'est intéressant is often sufficient in academic contexts.
