While these clips are supposed to be of aikido, they appear to be of people doing judo very badly. It certainly doesn't look like it would be effective in a streetfight. In its own way, the Shodokan stuff in these clips is as "unreal" as the more classical aikido styles are accused of being - only its a lot uglier.
All formalized interactions are unreal to a certain extent. One of the goals of Shodokan is taking kata and making it work more organically by letting people practice waza and kaeshiwaza more freely. It's much more difficult (I think) to make a specific technique work than to let principle form the technique "spontaneously." And I think that has a lot to do with why it aint so pretty.
