Six years after the death of David's father, his mother meets Mark. David then begins seeing his dad as a ghost. Neither father nor son like him - in fact, none of the new family's siblings like any of their new unit. Naturally, the kids resolve to make the 'other' parents' lives hell.
Somewhere in here there's a good idea trying to rise to the surface, and for its admirable intention of exploring - with greater and more honest detail than most, the 'you'll never replace my parent and I hate you' aspect of step-family living, David Cohen's efforts can be commended - but that's all.
The key problem is inconsistency: small moments of great, honest performing are butted up against others of hamfisted under-direction and inept improvisation; the story sets up far too many threads, some of which are never concluded (it even decides to open a huge, new one in the final reel). It's also let down by the amateurishness in which it's put together particularly the ultra low budget special effects, and the clunky editing that robs every scene, and thus the film overall, of any kind of rhythm.
With something to say but no idea how to say it, this is a film as frustrated as any of its' characters. It's clumsy so much so that any verve in the story gets trampled, but it's not unwatchable.
