This movie was literally the middle of the road for me. To me, it had more wrong than right, but I'll just give it a 5 and move on.
I really struggled with this movie, as it didn't seem to know what it wanted to be. Was it a comedy? A mystery? A farce? Except for the main characters, everyone else's hair, makeup and clothing were WAY over the top. A lot of the characters just seemed like caricatures of real people - that makes it hard for me to feel like I'm getting to know them and to feel empathy for them. Most of the characters were a little creepy, including the children. Was that so that we couldn't figure out who the "bad guy" was?

I think the biggest question I had while I was watching it, how did the FL get on board the ship without a ticket, how was she able to remain on board once the ship left (the ML knew she didn't have a ticket), where did she get her wardrobe since she didn't have luggage? And I could be mistaken, but when we first meet her, I don't think she even had a purse on her.

All-in-all, for me this movie was too "campy" and difficult to take seriously.
