Well acted, nicely shot, and with a solid score, this is a decent feature. It's only real flaws are an extremely derivative, and occasionally confused, plot; and some slightly clumsy dialogue at times.
It looks good, without being spectacular, which entirely suits its council estate setting. Combined with excellent performances from the leads, it could almost work as a pure kitchen sink drama. Despite not being given much to say, Harry Treadaway and Greg Wise are a convincingly troubled father and son. The support is also broadly good; Tom Felton is particularly notable.
The troubles come with the exasperatingly unoriginal plot - it borrows and from a whole selection of similar films. The good news is that it does choose some of the best to steal from; the trouble that it isn't good enough to stand up to these classics. However, it holds together well, at least until the latter stages, when a few too many extraneous ingredients are thrown into the pot.
Broadly, a decent effort if not outstanding. Given the mechanics, I would be interested to see future work from the team behind it - they just need some more original ideas to start with.
