Definitely worth seeing. There is a lot of rubbish out there generally. A big budget and big hype certainly do not make a good movie but they make the general public and, even I am ashamed to say, me, more likely to see them. Which is unfortunate not least because movies like Gamerz can easily be overlooked.
The story does not involve complex characters, what it does have is believable and honest characters that are easy to relate to. Its a feel good story which doesn't try or pretend to be more. It's easy to watch with some genuinely funny moments. While obviously not produced with a big budget, It's well crafted.
