Dolphin scene (spoilers)
Overall very laugh out loud, maybe could have been a bit more interaction with the 4 of them and 'proper aussies' but good fun.
However
The scene where Neil killed the dolphin was met with awkward silence in the packed cinema I was in. Not sure how or why the producers thought that was funny - laughing at dead dolphins ? Realise it's just a fake etc but just wasn't in the spirit of the rest of the film.
8/10 for me.
