What are other countries opintion on Brexit

Australia here. Brexit is the only thing I seem to hear in terms of news regarding the UK. It seems that no one can agree on how Brexit should be handled, and it seems to be taking up a huge amount of the government's time, when they could probably be doing something productive. It also seems to have wreaked havoc on the government as well, first with David Cameron resigning over it and now Theresa May has resigned because of it. Is Brexit really worth that much effort? It just seems to come with so many cons, that I can't see how the pros would justify the time and political effort that's been spent on it.
