It was interesting.
It's about a three hour show. I found it mainly informative and helpful, though it was quite shocking (even though a person familiar with Novus Ordo antics could probably expect some of the stories Mr. Thomsen had to relay, they're shocking nevertheless).
He offered a strange opinion as a "proof" against the validity of the Novus Ordo which I wouldn't use. Essentially, on the hypothesis that charismatics are possessed (since they meet three of the four criterion for discerning possessed souls according to the Rituale Romanum) they can "withstand" Novus Ordo "holy water" and hosts consecrated in the Novus Ordo. But if they were posessed, they couldn't "handle" holy water or the Blessed Sacrament. But if the Novus Ordo rites of orders aren't valid, then the Novus Ordo holy water and holy communion aren't valid, which would explain why the possessed aren't bothered by them.
I actually agree with him, or am tempted to-- but that's a circular argument and I certainly wouldn't present it to someone not yet convinced of the invalidity of the Novus Ordo rites (or, at least doubtfulness of them) as "proof." It's more an interesting after thought, these two likely hypotheses working in consort with one another, rather than strict proof.
It was also very interesting what he had to say about the SSPX after the death of ABL. Sound familiar?
