You have the original Wrath of God spell.

The effect or spell that allows you to sacrifice or bounce those things would be in the Instant batch.

The counterspell would be in the Interrupt batch.

The big difference is that once that counterspell is on the stack, you can't cast any more Instants.

So let's say that instead of countering the Wrath, you counter the spell that's bouncing all of the things. With the old system, that's it. If I don't have any Interrupts, we need to resolve our batches. No one can cast an Instant until we resolve both the Interrupt batch, the Instant batch, then the original spell.

Counterspells were even better before. They were effectively the last word. The stack kind of depowered them, but it gave a lot more play to the game.
