Define “New.” Like last year or so? For scifi:

Dune 1 & 2

The Wild Robot

Furiosa

Kingdom of the Planet of the Apes

Ghostbusters Frozen Empire

In that order, more or less. Aliens Romulus is not terrible but there’s a movie with virtually the same plot that’s a lot better called Alien (1979) that you should watch instead.

For fantasy:

Poor Things

Wonka

The Marvels

Poor Things is a real treat. Wonka is a musical. Marvels is superhero fantasy and Sci fi mixed.
