We picked up the Indiana Jones trilogy a while back. The boys had seen some YouTube clips, it was on sale, yadda yadda.
We watched the first one together a few weeks ago. Pretty intense, some scary parts, some bits above the boys' heads, but overall they liked it very much. I was left thinking "maybe we should have waited another year or two, but it didn't seem to do them any harm and they liked it".
Then we got around to the second movie, which I hadn't ever seen.
