Short answer: it seems unlikely, as almost every UK Government since World War 2 has been a single party majority government1.
Long answer: Firstly, to correct an error in the question:
This means there was all across UK more voters who choose a particular party than voters who choose any other opposition party.
No; the Conservative Party achieved 50.8% of the seats with 36.8% of the votes.
Such an outcome is a feature of the first past the post system used in the UK and other countries, combined with a purely constituency-based parliament, whereby a general election is, in effect, 650 separate elections, one for each constituency in the country.
The possible disparity between share of the vote and share of the seats tends to skew the latter in favour of the larger parties, and so some form of proportional representation is often called for, especially by the smaller parties.
In the meantime, the current system has tended to produce single-party governments in the UK. Whether this is a good thing or not appears to be a matter of opinion.
The hysteria in the media before and after the 2010 election, and especially in the run up to the 2015 election, suggests that it may depend on what you're used to. The UK isn't accustomed to coalitions, so many believe that single-party governments are better.
Conversely, in countries like, say, Germany, coalitions are the norm, and seem to function effectively.
To address a couple of other parts of the question:
It means that chances for any other party the ruling party to pass any law are slim to none
Not necessarily. In countries with a bicameral legislature, there is often no guarantee that the governing party also has a majority in the upper house, so some negotiation with other parties may still be necessary.
the ruling party can pass whatever laws it wants as long as there is no internal opposition.
That can be a very big problem. The new UK government has a majority of just 12 seats, which means that it is very sensitive to internal rebellions.
