I'd waited on this one a bit, I almost saw it in the cinema (it vanished before we had a chance), and I almost bought it on DVD when it first came out, but I bought something else instead. Saw it for six quid though, and figured why not? Nabbed it, watched it, rather enjoyed it. It's not Shaun of the Dead (in terms of British horror humour), and perhaps the segway from kidnap caper into horror caper could have been handled better), but it was a decent effort with plenty of decent fun to be had.
I'd have liked the horror aspect to have been darker, scarier, far grimmer than what we got - but there was certainly a satisfactory air of 'Ed Gein's farmhouse of horrors' about the final stretch.
I've not seen London To Brighton, well I've seen bits of it, so I can't really compare The Cottage to that...what I can do is compare it to Severance, another low budget Brit 'horror in the country' outing. It's not fantastic, but it's far from shit ... aye, I'll leave it at that.
