The Royal Hotel is a well-acted film, with particularly strong performances from Henwick and Garner. However, the film's slow pace and lack of suspense eventually become its undoing. The film is more interested in creating a sense of atmosphere and dread than in telling a compelling story. Unfortunately, it never quite succeeds in either.
One of the biggest problems with this film is that it never really gives the audience a reason to care about the two main characters. Liv and Becky are thinly drawn characters, and their motivations are never fully explored. As a result, it's difficult to feel any real tension or suspense when they are in danger.
Overall, The Royal Hotel is a disappointing film. It's a well-acted film with a great atmosphere, but it's also a slow-moving and unsatisfying film. But I wouldn't call this film a thriller as it offers no thrills or much suspense for the audience.
