Planetarium: Never delivered on it’s premise

Here’s a one-word review: TERRIBLE! here’s a two-words review: ABSOLUTELY TERRIBLE!
Now that we have gotten that out of the way, let me explain why this movie is terrible.
Here’s the synopsis to this movie: Follows the journey of sisters who are believed to possess the supernatural ability to connect with ghosts. They cross paths with a visionary French producer while performing in Paris. The producer coax them into agreeing to live with him when he tried to capture the apparitions on film and make the sisters famous. Great premise for a movie, right?
By now you think, wow, this could be a very intriguing movie. Here’s where the TERRIBLE part comes in. This movie did not even show any scene about connecting with ghosts, or a full fledge seance, or even a good scene where it shows any apparition caught on film. Nada. Zip.
Instead, it showed a very staged belle epoque party scene and mostly about the Natalie Portman character navigating her way around a movie that she was put into by the aforementioned producer when he went around perfoming some quasi experiment on her sister who purportedly is a psychic.
A total let down because this movie have a great premise that could be a cool paranormal movie in the vein of THE PRESTIGE. But nothing could be further than the truth. This turned out to be a bait-and-switch genre of French/English period-drama disguising as an intrigue paranormal flick that did not deliver, big time.
I won’t even categorize it as a suspense, not to mention, a horror.
