I am afraid of heights and this film made me sweat. Fantastic filming although I suspect a lot of CGI, but very effective.
There are some questions about the some of lack of professional preparation by the girls climb. Suitable clothing , equipment etc, I found it very irritating.
Also I would drop a ring into an electric connection ...lol.
The end ( rescue ) could have been another chapter in the film, but was totally ignored which spoilt it for me.
Overall its a great film if you get past the technical side.
