An improvement on 3.
'Rise of the Footsoldier 4: Marbella', like two of its three predecessors, isn't good. However, this one is more of a less serious outing for the series. It still features the, let's be honest, cringey wannabe-esque gangster stuff, but this one probably has the most comedic intentions. All the issues from the earlier films remain, in truth.
I never really cared for the main plot, though I didn't have a bad time watching it unfold - it's lame, but just about watchable. My 'favourite' part of this is the, unofficially titled, Adventures of Tony & Craig - they practically go on a road trip and it is amusing. The ending is kinda humorous, too.
Cast-wise it's, like all of the 'Rise of the Footsoldier' productions, average at best. Everyone gives a forgettable performance unfortunately, Craig Fairbrass has enough about him to lead satisfactorily but there isn't a true standout. Cool seeing boxer Conor Benn portray father Nigel though.
I see a fifth film is on course to land later this year. It's actually impressive that they've managed to craft this many stories from the one, true life, event. I plan on checking it out when it's released.
