If you're over the age of 12 then I'll stick my neck out and suggest that this film is not for you. I saw this with my two kids (aged 8 & 10) and they loved it. They haven't stopped going on about that matchbox creature.
For me, it reminded me of the films I saw when I was a kid - it's not a Marvel film nor a Harry Potter by any stretch but a low budget film aimed at a young audience. If you've got kids under 12 then I'd say give a go - they will love it.
Bye-bye.
