Over a million voters isn't a big difference? 2/5 last elections won by the loser of the popular vote seems extremely problematic.
Phrased differently, Democrats have won the popular vote in 4/5 of the most recent elections but only won office in two of them. In the 21st century, winning the most votes for president only results in a 50% success rate for Democratic presidential candidates.

Well, no, because it was designed this way. Popular vote is the obvious option when designing a democracy. They decided to go with something else under the specific understanding that any system other than a popular vote would allow this to happen.

It will always affect Democratic candidates more negatively because they don't do as well with rural voters and the electoral college exists almost specifically to give rural voters more power. This is by design--not an oversight or misunderstanding.
Read up on why the EC exists. I think the term that applies is "concurrent majority".
If you want a counter-example, you can look at small town and rural upstate NY and realize how their concerns are always neglected because the sheer number of NYC voters drowns out any chance they have to be heard as part of the electorate.
EC exists because the states had to agree on a mutually acceptable compromise (between large and small states, and also between slave and non-slave states) when forming US. It doesn't make it inherently valuable - it was a compromise solution, which pretty much by definition means that it's not a perfect design.
BTW the estimated popular vote is between 0.7 and 1.3% in Hillary's favor at this point , according to NYT http://www.nytimes.com/elections/forecast/president . Not really a big difference.
