Rubbish.

Everything about 'The War with Grandpa' just feels off, nothing feels right to me. What doesn't help is that the first 25-30 minutes are extremely dull, like utterly and truly boring. Once the premise gets underway it slightly improves, yet still produces nothing to remember. Even the 'war moves' that feature fairly cool scenarios just come across as very underwhelming.

The acting across the board is subpar, at best. That's a major disappointment, given Robert De Niro (Ed), Uma Thurman (Sally) and Christopher Walken (Jerry) are involved. I don't necessarily feel like they weren't trying or anything, but I just didn't sense any spark from them. The kid actors, meanwhile, are average.

Despite a relatively short run time of 94 minutes, I was gagging for the end credits for a rather long while. With that said, knowing me I'll still probably check out the apparently upcoming 'The World War with Grandpa' sequel in a few years...
