There's little to no character development, and the dialogue is tepid and uninteresting, providing no humor or spark to make us care about these people.

The acting was fine, the cinematography was fine, the set design was brilliant, and the special effects and sound effects should both be nominated for Oscars.

But without characters that I give two shits about, I can never get lost in the movie. It's an intangible that I take for granted when watching movies, cuz I usually get sucked in. I had trouble getting sucked in at many points of this movie.

It's still a good movie, well-directed with gorgeous special effects and some truly scary moments. But I'd certainly pause before throwing the word "GREAT" around.
