Overrated (some spoilers)

There have been some negative comments in appreciative topics so I've decided to start a negative topic on this ridiculous film.

The first hour really seems like a show on Travel Channel with a Portugese mother/history professor and her over-inquisitive daughter visiting massive tourism hotspots in the Mediterranean (where they interrogate fishermen about their family status and occasionally discretely join a group of tourists who actually paid for a guide) while on cruise to meet the husband/father. It was mildly interesting, but purposeless.
Then we listen to a dinner party at the captain's table, consisting of a French entrepreneur, Italian model, Greek actress and American captain. Each speaks its own language, yet they all understand each other perfectly. The conversation is extremely simple though (e.g. some people want a family and some don't). The dinner repeats the following evening with our tourist couple as guests of the captain, only ... THERE'S A TIME BOMB ON THE SHIP!!!
I won't disclose the final ending, but "wtf" sums it up adequately.

Someone mentioned the director was 95 years old at the making of this movie, so this could be the reason for its adagio tempo and basic level. He probably also noticed that American film had become rather sensationalistic, so he decided to plant a bomb on the ship to spice things up a bit and make it more marketable.

But I don't understand why some cinema veterans start appearing in films unworthy of their legacy. Do they at one point in their careers decide to do only films of their liking and just have a poor taste? Are they desperate to appear on screen again? Have they run out of money? Either way, judging by the lack of acting by the star actors of the dinner party, they just owed someone in the film crew a favour.
