I was also quite impressed. Rather than all the weird tweets and other odd things in the past two years, he covered it all and delivered it well. He acted "very Presidential" last night. THIS was the Donald Trump that won the election.
He remained polite to the Democrats and they responded in kind, imo. Even Nancy Pelosi treated him with respect which surprised me. She didn't at all during last year's SOTU address.
On the comical side... The speech lasted about an hour and a half with constant standing, applauding then sitting back down at least a hundred times. Whew! I'll bet you at least half of his audience last night woke up this morning with very sore leg muscles. That speech gave them quite a workout. Especially all the old farts that run our country LOL ;-D
