Having a choice between bad and worse and having to choose the least worst option certainly is a very bad thing.
That is what happened in France, Macron ou Le Pen.
I fear it will lead to apathy and extremism the next time round unless there is a viable alternative to neo liberal Macron.
That's the question though, isn't it? As I said above, the nature of politics is that you, by design, have to appeal to as many people as possible. Dave probably likes the Greens precisely because they're never anywhere near power so don't have to compromise, but it's almost certain that if they were in contention for government they would have to do so and would thus probably be less appealing to Dave.
The hoohah over pension reform is a good example, as you'll probably not be able to find a demographer anywhere in the world that doesn't think that as society ages people need to work longer. It's probably as close to a consensus as is possible to get on these matters, yet the moment anyone dares to suggest such a thing people take to the streets and start burning things. Granted, Macron went about it in an oafish way, but I doubt anything would have happened otherwise.
The Brexit vote was similar, in that it ignored expertise and went instead for nice-sounding fairy tales. People "could" have read up on things and become better informed, but they chose not to and thus Brexit happened. So we kind of get the politicians we deserve.
