I find the animated videos to be more helpful than the crew-demo versions. Here's why:

The animated video shows how to open the door - handle rotation, streamer, all of that. The crew simply point to the door. Same with exit locations throughout the plane, life-raft locations, etc.

Big surprise here, I was on a BA flight where the AVOD failed. I'm sure that's never happened to anyone. So, the crew had to manually demo the safety information. It was visually interesting simply because it was choreographed perfectly. Every crew member in the same position, same movement, both sides of the aisle. I've never seen anything so well practiced on any other airline.
