Reviewer notes
Not recommendedRubbish. Everything about <em>'The War with Grandpa'</em> 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.…
RecommendedTrusted family reviewersSit down, let the screen light up and enjoy the distraction. This is an amazing collection of actors having a bit of fun with a script that's something a little different.

This is definitely the kind of film you'll watch once with the family, then forget it ever existed.…
