Manager Stuart McCall expressed his frustration at Motherwell not getting their third Tannadice win on the trot.
Henri Anier gave the Steelmen at half-time lead, but Dundee United scored twice after the break and only Lionel Ainsworth's strike rescued a draw.
"I think it's two points dropped," McCall told BBC Scotland.
"At half-time, we looked in control of it. I thought we had two or three good attempts to go ahead even more in the first half."
Early on in the match, Stephen McManus's diving header went a yard wide and Anier subsequently lashed a shot over from the edge of the box.
The Estonia international did score his fourth of the season clinically after Zaine Francis-Angol had delivered from the left following a great run, but McCall felt they should have had more.
"They've got a young side and, if you can score first and control the game, we could've gone on to win it," he said.
"I suppose coming to Tannadice and getting a point, in the grand scheme of things, is not too bad.
"Credit to our lads for coming back after getting hit with two sucker punches. Both sides went for it and, in the end, it was a terrific game."
United striker Nadir Ciftci equalised for the hosts before 19-year-old Andrew Roberston netted his first Tangerines goal in style from distance.
"It was a great goal from the left-back, but we've let him come 60 yards unopposed and we've got to go out to him at a certain stage," McCall said.
"I'm disappointed with the two goals we conceded, but you've got to say it was four excellent goals."
The best was kept for last, with on-loan Rotherham winger Ainsworth coming off the bench to hit a 30-yarder into Radoslaw Cierzniak's top corner.
"I've not seen that in his locker," said McCall. "Chris Humphrey hit one like that last season, although it was more on the break."
