영화가 좋아요 means "I like movies."
More precisely, 영화 보는 것 좋아해요 will sound more fluent, which is "I like watching movies."
If you'd like to say "I like the movie," you should say 그 영화 좋아요. This is direct translation, but if you want to sound like a native speaker, you should consider saying 그 영화 재미있어요, which is "The movie is fun."
Hope it helps :)
