+1 jenett's suggestion re: ways to find stuff to watch. Am not opera fan but know Some Things (another taint, hurray, but mostly I don't really enjoy that particular mode of vocal ... to me it scans as distortion).

I don't think that English subs are crucial, actually. There are translated libretti? In the moment, the viewer should focus on the performance as conveyed, IMO; if they want to look up what the lyrics mean, great, but there's power in a solid perf without it. Reading along can distract, I mean. Just my two cents.
