Healthcare costs have always gone up every year. The reality is that healthcare costs have gone up under ACA at half the rate of the pre-ACA increases (3-4% under ACA, vs. the 6-10% annual increases every year for decades!). That's better.
As for worse insurance, that's unlikely. For example, the insurance companies aren't allowed to waste more than 15% of what they are paid, when previously there was no limit. And they were allowed to take insurance away from people that had been paying for it, if they became sick and required expensive coverage. And they were allowed to refuse to insure people with "pre-existing conditions" so people could lose coverage if they switched jobs. And they could sell insurance that turned out to be worthless. And the leading cause of bankruptcy in the US was medical bills to PEOPLE WITH INSURANCE who were driven into bankruptcy by their insurance companies. All those practices are illegal, making everyone's insurance (and lives) better.
And hospitals don't have to lose a fortune on providing services to uninsured people, which they covered by inflating the charges on the insured patients. So because the uninsured rate at hospitals has dropped dramatically, hospitals can stop having to cover the loss. Which is one of the many reasons that healthcare costs have stopped skyrocketing.
And 10m people have insurance that didn't, and will therefore lead healthier lives, which is an ethical improvement. If you care about people.
