It's a movie series set in an old timey fantasy world so it's not going to seem dated the way an 80s movie like The Breakfast Club or even Ghostbusters might seem dated. That said I don't entirely buy your premise about freshness if by that you mean quality. I'd say Ghostbusters still holds up much better than the majority of modern hollywood movies even if it used a different style of film stock and different special effects.
