here's a fun little compilation of Ultra Seven from the 60s to the more recent Ultraman Mebius. it shows his transformations and various powers- neat to see how the effects have changed throughout the years, and yet they use the same basic ideas. and sound effects, those make it hold together very well.
I really must look into getting the new Ultra Seven DVD sets. it's probably the one Ultra show I think would be better subtitled than dubbed. neither English dub that's been produced has been satisfactory, alas. the scenes are set to the Song of Ultra Seven (I think that's it).
