Delighted to see that.
The guy is obviously missing out on some things that niche-within-a-niche Irish modellers would know, for example "SuperTrain", which is understandable if he's young, British and hasn't experienced certain things for himself.
His issues with design / packaging / information are valid, and supported with evidence, ie are constructive criticism, but he does not allow these to take away from an otherwise outstanding model.
Hopefully, manufacturers in general learn from the comments of influencers such as him.
I see some commenters underneath his video suggesting IRM wagons to run with the 121, and suggesting that he reviews an A Class. If he does an A, hopefully he understands the relationship between IRM and Accurascale, and thus what the A means for future UK locos. It'll be a while before my own A's get here, but from what I've seen here and on YouTube, Sam will be blown away by the A.
Sam's Trains takes a beating on here, but I suspect that some of that is prejudice rather than judgement.
He addresses the unsuitability of the custard and cream coaches in his video, so is obviously well aware how blasphemous that is.
Hopefully, somebody tells him about IRM's Black Friday sale tomorrow and he gets himself a load of wagons to review!
