Older episodes of RadioLab are absolute gems. Around the time Robert Krulwich retired I noticed a palpable shift. The new hosts' motivation shifted from inform to influence. It still has good stories, but the framing is somewhat more manipulative, in a way that's hard to pin down but makes me distinctly uncomfortable and sometimes exhausted.
The way Radiolab chops their interviews into tiny little pieces and then glues them back together with snippets from the hosts is basically the best way to make sure your guests always tell the story YOU want them to tell...
