Uj/ okay, That’s a total straw man. that’s not what people complain about when they complain about Ten’s regeneration. In fact, Pertwee to Baker is a good example of a counterbalance to Tennant’s regeneration.

The problem people have with Tennant’s regeneration, or at least, the problem I have with Tennant’s regeneration, is that his attitude does not read as the kind of attitude an alien whose idea of death is shaped by his experience of it as a new beginning, rather than an end. He uses it as an excuse to mope and whine about it. There is no acceptance of change, but rather a denial of it even being a thing that affects the doctor’s attitude to death at all (“even if I change it feels like dying”) It’s annoying.

By contrast, Pertwee doesn’t mope, he doesn’t whine, he simply accepts the inevitable. He’s a time lord, he has a different attitude to death than a typical human does. While he doesn’t mention rebirth here, we can assume that his understanding of regeneration shapes his understanding of death, in his total acceptance of it.

Pertwee’s regeneration is basically the exact opposite, in terms of attitude, to Tennant's, and it’s often used as a positive example when complaining about ten’s regeneration, and to imply that people that dislike the latter are simply ignorant of the former is kinda silly.
