An above average spirt summoner

Summoning the spirits and the inevitable consequences may be a familiar theme, but I thought this movie had enough ideas of it's own to keep it fresh and interesting. I wish it was scarier though, and that I liked the characters more.

Decent

A decent looking and interesting story with plot twists that, while not completely unexpected, keep things interesting. After a while it started to drag a bit, and I found the visitor so unpleasant and annoying that, instead of sympathizing with her, I wished mother would have gotten rid her.

Good fun, but it's really only comedy

Having all female leads was a good move to make it fresh, and overall I had a good time with this colorful and frisky comedy. It's predecessors, however, also threw in some genuine scares in creepiness in the mix, which made for a more exciting, balanced experience than this.

Perfectly fine but not so subtle group dynamics in space

It seems reasonable to deem it "Lord of the flies" in space, and I see no shame in it. I liked it. It's just that the emergence of the 'bad group' seemed forced and rushed. It would have been more interesting if they had genuine and reasonable different views instead of just being jerks.

a bit cold

Characters and atmosphere are a bit cold and unsympathetic, in an otherwise amusing and nicely found road/drama/love-movie (with a dash of sci-fi).
