I get what the director and writer Isabel Coixet was trying to accomplish with It Snows in Benidorm. The idea was to create an ethereal story about a fish-out-of-water gentlemen who gets a new lease of life. The story about finding a missing brother is just a McGuffin. Nothing is resolved and that story just plays in the background as an excuse to meet new characters.
The problem with the film is not just the pacing but the idea that there is a degree of other worldliness with Benidorm. Lots of the shots are done in slow-motion with an esoteric soundtrack, to imply importance or mysticism. These are done when we watching a hen party, the nightlife or when Alex is seeking out Peter or visa versa. It is basically trying to be like the film Babel or Disconnect, but unlike those two films, ISIB has nothing to say.
This is a great shame because Timothy Spall is an amazing actor and in here he is wasted. The film either needed to be one thing or another. It either had to be about Peter trying all avenues to find his missing brother (think Get Carter) or it had to be about a shy reclusive man finally coming out his shell (think Being There). With the juxtaposition of the two story lines, it does not satisfy either one.
Finally the character of Peter did not feel real. As a deputy bank manager, Peter comes across as too naïve to feel credible. There was also a bit about a Spanish poet that obviously means something to Coixet but left me indifferent.
Also I very much doubt any Spanish taxi driver would be remotely interested in talking about Brexit, a subject even the Brits are fed up talking about.
