Agreed on all fronts. Those Tokyo lines are insane at rush hour, and almost dead silent at every other time; it's kind of the nature of homogenous commute types, it's just hella more efficient to do it with trains than anything else we have. Thankfully, the new subway extension should help distribute people a little more evenly, and I believe TransLink is looking start running longer trains, which should provide a little more capacity at peak times.
