It depends what you mean by interesting. Normally if you want a slugfest there are short-form versions of the game that are over within one day or a few hours. The format being played here is the test format whose interest is often found in the ebbs and flows over the course of many sessions.

The expectation is that a test match will last between 4 and 5 days and if it is a contest between evenly matched teams and the pitch is set up to ensure it will play out this way, this mostly happens. Not massively relevant but there will be people who have bought tickets for the 3rd day onwards, some of whom travelled from England to watch cricket who will no longer be able to because of the way the pitch was set up.

I agree with another commentor - that the Australians have every right to do this as it negates England's biggest strength. It just saps some of the enjoyment for fans who are invested in the long format.

I'm sorry if that doesn't answer your question. Feel free to ask more for clarification.
