I rate the initial idea behind this movie as good. However, first of all the way they tried to make energy does not sound very logical! Also, they just mentioned jargon such as Mtheory and Parallel universes possibly without knowing which one is related to what! And parallel universes here are basically parallel earths! This list can go on and on; therefore, the science part of this movie have some problems. But I’ll give it a pass.
Then we get to the story telling part of this movie which is absolutely poor! Things just happen without proper causes! People pass on using cars or bicycles and prefer to just walk and run far distances! Bullets avoid hitting heroes and explosions avoid harming them at all costs for most parts of the movie! Also, there are big plot mistakes regarding things that happen on parallel universes.
All in all, I would have gave it a 3, but since it has good CGI, I gave it 4.
Would I recommend you to watch it? Only if you are bored to death and you are out of good SciFi movies.
