Some countries that became more democratic over the past 10-15 years would probably include places like Tunisia, Pakistan, Myanmar, and Georgia (to name a few).

It's a complex issue, and like others have pointed out, being democratic isn't a binary switch. Take Turkey, for example - in a country prone to military coups, the most recent military coup failed. Erdogan has autocratic tendencies, but people really do support him and he seems to be in power because of mostly democratic elections.
