That really don't add nothing of interest in the saga and they don't even bother of sticking to the main entree, with the sole exception of some of the original cast appearing again (here, of course, the spotlight is all for Noemi Morinaga, as lovely as she was in the original series and in her following JAV work) and some slight reference to the nature of the original series, reference that is bogged down by content that has NOTHING to do with the original series in the slightest, with the worst offenders in this case being the new Shaider presented as a womanizer of sorts - the kind of which Dai Sawamura as performed by Hiroshi Tsuburaya (R. I. P.) wasn't - and the inclusion of a love story between the Shaider and his sidekick that wasn't really there between Dai and Annie. All given to you by none other than Naruhisa Arakawa, which extremely good work in Abaranger the more time it passes the more looks like a Dennis O'Neil case of a person doing one thing of excellence (The 70's Batman, in the case of the latter) amidst a general mediocre/bad quality in the output. Hell, this movie even fails at the fanservice level, with the Iconic with a capital I panty shots of Annie replaced by inguinal shots of some of the female cast (and a torso shot of the new Shaider for the ladies) that, again, no matter how enticing they are, they have nothing to do with the original series to begin with and they don't add nothing of interest. If I were in you, I wouldn't bother. Watch once the first Shaider movie (NOT the second) AKA a standard episode of the series presented as a movie because Toku movies spinoff of a main series and it will suffice. At least it had Annie's panties in it.
