Fun fact: Every time people use the word "animations" instead of "animation", it makes animators over 40 cry.
As for display animation, B/W and Stern had excellent animators working within the limitations of the DMD, due to one word: TIMING. Timing is what makes animation fun, pop, and leave a lasting memory. It's not about resolution or polygons or looking like AAA video games...it's timing. Take a look at what's going on with the animation of Metallica, AC/DC, Simpsons, Family Guy, MM, AFM, MB (or any B/W game, really)...from an animators standpoint, everything you see "plays"...even though the limitations are dots, you know exactly what you're looking at, and the timing is excellent & memorable. The comedy is sold...the action is sold..because the timing is tight and well animated. Timing is what's generally missing in today's pinball display animation. It's either even/floaty "flash" style, or weightless wonky 3D models. This is what makes modern pinball animation look dated: funky timing.
