Not really, at least for the core. I will give you that he has done several things but most of the big ticket items have been forgotten about. He promised tax REFORM and delivered the same old tax cut in its place. That has been glossed over and forgotten by most though so I can give him that. The ACA is still in place. No border wall. Iran deal still in place.
He did pull out of the Paris Accord. Of course that is more symbolic than anything as those requirements were voluntary in the first place. Stopping the TPP is something that he had promised his base and followed through. He has rolled a lot of regulation back as well - another victory there.
All in all, there were two major centerpieces to his election and issues that his core cares most about - ending Obamacare and building the wall. Obamacare did not end and the wall is not getting built. Further, Trump is on record advocating for another round of amnesty. That has [pissed off a lot of Trump's base particularly as many were single issue voters voting on the wall.
People can say what they want about Coulter but she is hitting on a sore spot with a sizable portion of Trump's base.
The Obamacare mandate DID end, the Muslim countries travel ban is still in effect, ISIS is floundering, if existing at all, affirmative action has been challenged, and lots has been done on immigration (see link). >>

As for DACA, I theorize that Trump knew the Democrats weren't going to accept his deal, so he could offer an amnesty, watch it fall, and then blame the Democrats for going against the DACA people. Shrewd. Sometimes trump's methods are so unusual and shrewd that it's hard to pinpoint what he's actually doing.
And I would not call slashing the Corporate tax, "same old tax cut"
