Too Unrealistic
29 January 2006 | by patrick_dunneSee all my reviews

Imax made this film. It's about a girl named Ally, who has troubles with her dad. For example, she thinks that the T-Rex may have laid eggs, even though an egg has never been found.

One day,her dad finds an egg. (T-Rex perhaps?) He brings it into his office, where Ally is working. Ally accidentally knocks over the egg, and some weird gas is released from it. Soon, Ally begins to somehow hallucinate and imagine that dinosaurs are in the museum.

The film is an adventure film. That's all. With the exception of some possible drama between Ally and her father, T-Rex: Back to the Creustaceaus is just an adventure film. No thrills. No action.

But, it does have some decent 3-D effects. However, the effects are not used to their full potential.

Overall, T-Rex: Back to the Creaustaceus is decent, but pretty boring and unrealistic.

Good: 3-D effects, and a running time of 45 minutes

Bad: unrealistic, silly and it doesn't have thrills, excitement, shocks or action. 3-D effects are used to a minimum.
