You can ask what he MIGHT have thought, but to treat it as gospel or to even place so much on the opinion of Honda seems ridiculous. The franchise as Honda understood it and where it was even by the end of his life were very different. It's like that era of the fandom in which THE 54 FILM IS THE ZENITH, ALL ELSE PALES AND STAND ILLEGITIMATE IN ITS WAKE mentality overtook everything. Things change, and this franchise has done so a great many times.
Oh my god, is this where we are? "THE TRAINS DIDN'T LOOK REALISTIC." (also choosing a gif of something that just looks interesting, great choice *thumbs up* and all that)
As for the trains, I like it too, I like how strange it is, as though the cars are bumping into one another and locking into serpentine shapes. It looks like they're swarming him. It's almost like Tokusatsu doesn't value realism over visuals. Though I'm sure there's no hint of that in the franchise's history.
As for a masterpiece, that's always gonna be swathed in opinion and that's why much of the "THOSE JAPANESE AND THEIR NATIONALISM!" irks me. Just dislike the movie, this business of then dragging it into the quagmire of "THIS MEANS THIS" or "THIS MEANS THAT" (Again, I acknowledge it's there to be read) and doing so with such a definitive tone seems silly (not to mention seems to want to place a moral judgement on film thereby ruining the fun of film interpretation as a hobby)
I must've had a fit of madness, because I thought in the era of Shin Godzilla/The Godzilla Anime/an the Monsterverse stuff that by so many tones and ideas being expressed we might've moved into a stretch where everybody got to appreciate a little bit of everything, but instead it feels like certain groups are just clinging feebly to a niche of scholarly influence that is as fleeting as their own lives. We must box things off, and we have to decide what is True Godzilla or No. XD. This fandom is so funny.
