To be frank I don't know what to think about it... In terms of scientific research I don't see the interest, compared to a station in LEO. Well, except if we talk about observing the Moon (especially its far side).
I would rather see it as a step towards future deep space exploration, so that a crew can learn to behave in an autonomous way in deep space, to evaluate the dangers of space navigation... The solar radiations for example. In LEO the astronauts are still protected by the Earth' magnetic field, but they are much more exposed in Moon orbit (a solar flare would kill them!).
And of course on a geopolitical point of view that's a demonstration of power
