Here are my incredibly infomative and useful reviews for the 2 aforementioned films.
The Chronicles of Narnia: Prince Caspian – It’s ok(ish), drags on a bit, the story is a bit jumpy and the action is a bit flat.
Indiana Jones and the Kingdom of the Crystal Skull – Hmmmm. Harrison Ford looks bored, the story is a bit poopy™, I found Shia LaBeouf to be a bit annoying and the film was generally dull.
So…I present to you something a lot more entertaining than Prince Caspian and Indiana HuntingforBones…
