It does have problems, the whale is really just a transitional creature. If it was 'created' to live in the sea why would the creator give it lungs when gills would do the job just as well? The lungs are just a constant problem, it has to keep resurfacing, fish don't have to surface.
The cetacean branch of evolution (Dolphins, Whales, porpoises, etc...) all have the same attributes that support that cetacean creatures once lived on land. Genetically they bare far more resemblance to land mammals than they do fish. the Cetacean creatures all fall under the Cetartiodactyla order, which is a a group of animals that includes not just whales, dolphins and porpoises but also land mammals such as hippopotamuses. We've even found staged cetacean fossils in Pakistan that show the transition from land mammals to sea mammals.
Just out of interest the attributes that these animals share are defined as...
1. Their need to breathe air from the surface;
2. The bones of their fins, which resemble the jointed hands of land mammals; and
3. The vertical movement of their spines, characteristic more of a running mammal than of the horizontal movement of fish.

But the whale still lives well.

I think you are purposely choosing to not understand what I'm saying.
Whether it lives well or not is not the argument I made, sufficient evidence exists to show that it evolved from land mammals and was not created to live in the sea from day one. It may have adapted to live in the sea, but the evidence shows that it does not come from the sea and that it evolved from a land mammal. This can be seen in the wide differences between fish and cetaceans, etc...
The way it lives shows attributes of land mammals, if it had never lived on land why would it have these land based vestigial organs and attributes such as land adapted spine and lungs that were made for land?
To me the whale is merely a "transitional" animal that is going through an evolution from land based life to water based life.
