The writing is bad. The acting is uncomfortably unconvincing and self conscious.

Apparently boomers love this movie because it reminds them of that old, horrible style of who-done-it where a clever investigator makes impossible connections without the film letting the audience in on any of the nuances of discovery.

Novels like these were written as fast as people could type a hundred years ago because they were so simple, formula, and decidedly un-clever to generate.

Now, if this style appeals to you, I would still issue a word of caution.

This film clearly intended to assemble an ensemble cast that would bring life to its quirks and quips. The script seems to be intended to allow the cast to shine through what the author thought were interesting and audacious characters.

However, both the writing and acting come off very flat and even painful. The film that the creators intended is obvious, and clearly present throughout as a sad, unimaginative passenger repeatedly embarrassed by trite dialog and the unrealized aspirations of a mediocre cast.

This is a very bad film.
