It was OK. I was actually surprised at the lack of action and the scenes where all their enemies just get mown down by the bucketload became yawnsome after a while.
The acting was uniformly dreadful - the scene with Rourke and Stallone was actually painful - and the sideplot with Statham and his girlfriend/her new boyfriend was spectacularly bad.
I did think Eric Roberts was a delight though, totally hilarious and over the top. Also didn't realise Angel from Dexter was in it until he popped up chewing the scenery.
Still, it did what it set out to do, everybody in it realised there was no point even pretending they could suspend anyone's disbelief and it went down with a few bottles of wine.
Utter rubbish, but fairly entertaining rubbish all the same.
