Nope, the final design for the Montana was pretty damned good. The problem was BuOrd's super-heavy shell. Its penetration was very much on a par with other people's 18" shells and, as further developed for the Montana would have been even more destructive. That being the case, BuShips opted for a lighter main battery than she could have had (i.e., stuck with the 16" instead of upgunning) and still needed a 16" belt (as opposed to the Iowa's 12") , but she was still good for 28-30 knots, she had an immune zone against her own guns (with super heavy shells) on the order of 13,000 yards (it was 18,000 yards against anyone else's 16"), she had an anti-torpedo system that worked (unlike the South Dakota, Iowa, and Missouri classes, where the anti-torpedo features had been compromised because of fear of underwater shell hits at extreme range), and was a far better seaboat than the Iowas. With her designed radar suite (and let's not discuss the nuclear 16" shell developed in the 1950s for the Iowa's main battery, shall we?), she could have kicked the posterior of any other ship in the world once she got into gun range. Of course, that was the rub: gun range as opposed to airstrike range.
The real reason they weren't built wasn't that they weren't superb ships; it was that in 1942 (when they were indefinitely delayed) the USN needed carriers worse and carriers could be built much more quickly) and in 1946 (when the Navy wanted to reinstate frozen programs) no one else in the world had battleships except for our friends and close allies the Brits (the 4 surviving KGVs and Vanguard . . . for about three years) and the French (2 Richelieus). Had anyone else had comparable ships, or had there been any prospect of anyone else's acquiring true heavy surface combatants, they would still have been required if only to protect the flight decks.
Of course, nobody but our friends had carriers, either, which is the reason the USN had basically been slated for the junk heap in favor of the Air Force until Korea came along and those pesky North Koreans overran all the friendly airfields on the peninsula, at which point the navy sort of cleared its throat and said, "Ahem. We still have some carriers, you know, despite Louis Johnson, and if no one would mind too terribly, we'd sort of like to explore the possibility of maybe using them to keep our guys inside the Pusan Perimeter from being overrun and massacred. No offense, of course." (That last was just twisting the knife, I fear. )

Your mileage has varied.
The contrary opinion I was considering is found in Norman Friedman's United States Battleships An Illustrated Design history Naval Institute Press 1985, p. 342
"The final version, BB 67-4 of March 1941, was 60,500 tons, 890 feet long, with minor changes, primarily an increase in armored freeboard from 8 to 9 feet.
This design was circulated among commanders afloat, who were surprised that so little could be obtained on so much displacement. Commander battleships of battle force, for example, was disappointed that there was no increase in the number of secondary guns compared with Iowa. He could not understand how, on a reported displacement of 40,500 tons, the designers of the German Bismarck had crowded in a total of 24 secondary guns..."
