Indiana Jones and the Last Crusade (1989) 6.5/10
It's probably my favourite of the Indiana Jones movies, it's certainly the funniest. It mainly stands out because of the dialogue between Harrison Ford and Sean Connery, which at first there is plenty. Unfortunately later on the movie relies too much on the action side and it starts to drag a bit...though I do love some of the earlier action sequences(speedboat and motor cycle). I don't like the beginning with River Phoenix...
Indiana Jones and the Kingdom of the Crystal Skull (2008) 3/10
It probably has the best start to an Indiana Jones movie since Raiders of the Lost Ark, to be fair the whole first half is decent enough and I was just starting to think that maybe it wasn't as bad as I remembered. It's only when Karen Allen shows up that things go downhill fast, the second half of the movie is just corny with poor attempts at humour and lot's of ridiculous action. Most people seem to think that this is the worst movie in the series and I agree, a shame though because like I say it starts well.
Carry On Camping (1969) 3/10
While it can still be funny here and there, I spent more of the time rolling my eyes, it's terribly dated.
