You should like this film if you are a motorbike fan, if you liked seaside resorts as a kid, if you like gentle folk music, or if you were in the Brownies. In some ways it's a typical British film: understated humour, overstated contrasts between the good and the bad in English landscapes, various characters who overdo British stereotypes, and a hero who's a wimp; but it also carries the usual themes of a road movie, albeit more slowly than many road movies. It's also about "heart", in the figurative sense, which is about the only relevance the title has to the film ... except that the road trip goes across the central hills of England. It's obviously a low budget film, but it shows what can be achieved without big special effects.
