"everyone in the group thought the komodo dragons were interesting to see."

Explanation:

An infinitive is a verb form: to + verb.

An infinitive that modifies a predicate adjective is functioning as an adverb. In the sentence above, "interesting" is an adjective that comes after a linking verb and it is modifying the subject "Komodo dragons". Thus, "interesting" is a predicate adjective.

"to see" is, on its turn, modifying "interesting", offering further explanation. The dragons were not merely interesting. They were interesting to see. That is what adverbs do: they offer information on how (manner), when (time), where (place), how much (degree), and why (cause).
