A question about voting systems—unrelated to U.S. elections!

Jan Vecer writes about a new voting system that is now being considered in the Czech Republic which faces a political crisis where some elected officials became corrupted:

I came across a new suggestion about a voting system. The proposal is that in each electoral district the voter chooses 2 candidates (plus vote), but also chooses one candidate with a minus vote. Two top candidates with the highest vote count (= number of plus votes – number of minus votes) are elected to a parliament. There are 81 districts in total, the parliament would have 162 members if the proposal goes through. The intention of the negative vote is to eliminate controversial candidates.

Are there any clear advantages over the classical “select one candidate” system? Or disadvantages?

Any thoughts on this? I am not an expert on this topic but maybe some of you are.
