Short answer: Yes he was a talented speaker and a great manipulator. He knew what the crowd wanted to hear and he could express it very well. However, this is a great simplification.

Longer answer: The problem is we view his speeches from todays perspective. The world now is very different so we can only assume how germans felt at the time. If you are really interested in it, I suggest to read some books from Erich Maria Remarque. These show from the perspective of the time how it could have come to this. Germany, once a proud superpower, was devastated after the First World War. The heavy defeat, supply problems, hyperinflation and all that struggle, provided the breeding ground for all kinds of radical factions. It was no wonder a demagogue like Hitler was so well received back then. From today's perspective, this is not really possible to judge. The Allies knew that this could not happen again after the Second World War. Thats why the Marshall Plan was introduced, which led to Germany maturing into a modern western democracy.
