I think that the majority of the country is generally less comfortable with the idea of coalitions/minority governments/power sharing than many other parliamentary democracies where those things happen more regularly.

Consider the run-up to the 2015 GE when it looked like Labour/Lib Dems/SNP might be able to form a majority coalition even though the Conservatives were likely to be the largest party - there was a lot of sneering at the idea of a "coalition of the losers". That circumstance arises quite frequently and is largely accepted in many other countries, as can be seen from the results of Denmark's recent elections.
