Bare with me here, but ALL animals look the "Best" when they are babies.
In BPs, this is especially true.
One cannot really expect anything to look as cute or as young/youthful/etc when you get older.
Things fade, things sag, things... grow hair... etc...
I think that since most people only see the photos of baby BPs, that this mindset is forming that they look "uglier" with age.
I disagree completely.
They just mature into the tones in which they were destined to take.
So there.
PSSSSSSSSST...wanna know a secret? That's why you get blood pythons!!! They are truly the "fine wine" of the python world...the good ones just get better & better with age!
