The rise and fall of Blackberry, the world's first smartphone, it's journey from initial conception, to funding, all the way through to its tragic collapse.

I thoroughly enjoyed this film, it's one I would suggest that has a universal appeal, one many will enjoy, fascinating to think this is where it all started, everything about our phones that we now take for granted.

What a fascinating story this is, I'm sure many of us had a blackberry back in the day, I certainly did, it was such a reliable device, it was a game changer, until iPhone that is.

It's an intriguing story, with several jaw dropping moments, including the way Jim made his initial impact, then went on and assembled such an incredible work force.

A few funny moments, and some very sad scenes too, sewing Mike desperately trying to put something together to compete with Apple was quite tragic, after doing all of the ground work, the tide literally turned overnight.

Glenn Howerton gives a show stealing performance as Jim, he's angry, he's short tempered, he wants things done yesterday, he's a high powered, highly motivated executive, dealing with a team who live life to the chill, what a strong performance, that scene where Jim realises that the game is up, fantastic.

The whole cast are excellent, Jay Baruchel and Matt Johnson were both great. Seeing Mike change over time, that was skilfully done.

I was surprised by how good this was.

8/10.

Aside from the constant annoying fast zoom-ins and shaky cam "The Office" style filming - which I can't stand, this was one heck of an enjoyable film. The two hour runtime flew by with the excellent pacing and the smooth cohesive and well-written screenplay. Jay Baruchel nailed his character with an all around great performance, as did Glenn Howerton. For that matter, all casting and performances were spot on, as was the cinematography and score. The story was mind-blowing, even if you never owned a BlackBerry, just to see a slice of Steve Jobs as the Canadian version of a small start-up becoming a world dominating tech empire, and that empire's fall from grace.
