The idea is OK, some dinosaurs escape captivity and run wild.
But...
The acting is terrible. Some of the worst I have ever seen. Too melodramatic when they should be dramatic and way too dramatic when there was no need.
The special effects are horrendous! Jurassic Park had good special effects, Jurassic City just looked fake. The dinosaurs were on a slightly different lighting level to the rest of the scene. It reminded my of the original Godzilla movies.
The story had some stupid twists, stuff that would never happen in real life and one specifically which is so bad it made me wonder what the writers were thinking.
All in all, one of the worst films I have ever seen, but not in an annoyingly bad way, just in a "what am I watching" type way. If you have 90 minutes to waste then you could do worse than this one, but it will be a waste of 90 minutes.
