Where can you legally stream Barbie movies?

I'm a big fan of Barbie movies, especially from the older ones… Do you know where to watch them for free? On Netflix there are no and on YouTube only a few in poor quality. Are there any other alternatives?

Look at Amazon Prime, Maxdome… Or just on dubious sites.

"and only a few in poor quality on YouTube"

even if they were in 1080p, 4k or even 8k would still be in poor quality. The resolution does not change anything at all.

The resolution is there but at the maximum at 360p… Which I would not find too bad, but there are hardly any.
