It was unlike anything he'd ever seen before

"It was unlike anything he'd ever seen before"

Tengo entendido que "anything" se usa para oraciones negativas y, si esa frase es afirmativa, ¿no debería usarse "nothing" o "something"? ¿por qué se usa "anything"?

Es la misma de decir "It was like nothing he'd ever seen before" or "He'd never seen anything like it". No hay nada que ha visto como lo que ve en este momento.

Porque dice "unlike", "un" le hace una oracion negativa, y necesita usar "anything".

entonces:
"It wasn't like anything he'd ever seen before", "It was unlike anything he'd ever seen before" y "It was like nothing he'd ever seen before"
¿todas significan lo mismo?

Los dos últimos suenan un poquito mejor, pero sí todas significan lo mismo. Tal vez es un poco idiomático.
