I, and a lot of other fans, had a love/hate relationship with BRAVE AND THE BOLD in the 1970s.
On one hand, the great Jim Aparo made his mark on the series as the definitive Batman artist of the decade, despite never having a regular gig on the Dark Knight's solo adventures. Aparo's clean self-inked linework survives the translation to black-and-white here very well, and it's fun to see his interpretations of the many characters of the DCU. I always especially liked his Green Arrow.
On the downside, the series during this era was infamous for writer Bob Haney's callous disregard for (or ignorance of) the guest stars' continuity and characterizations. In this volume, we see Earth-2 heroes Wildcat and The Spectre (a decidedly less bloodthirsty version than was depicted in Spec's own series at the time) operating blithely alongside the Earth-1 Batman without explanation; multiple team-ups with an aged present-day Sgt. Rock (despite Rock's creator and then-writer Robert Kanigher's assertions that Rock did NOT survive WWII); the first very forced integrations of Kirby creations The Demon, Mister Miracle, and Kamandi into the larger DC Universe at a time when Jack himself was still handling the characters' own books; bizarre and out-of-character takes on the personalities of Plastic Man, Swamp Thing, Aquaman and others... the list could go on and on. Oh, and there's Batman's several references to his "bat-sense," which alerts him of danger (no, really). Because of all the anomalies, fans of the day kidded that B&B took place on "Earth-B," in a play on DC's multiple-Earth concept.
Haney was a veteran who broke into comics in the 1940s, and his logic-defying plots replete with wacky scientific and historical errors reflected that earlier era, flying in the face of comics' trend toward greater sophistication and realism in the 70s. These stories are more Silver Age than Bronze Age in nature, and aren't the best representation of the overall comics scene at the time.
That said, all the Showcase volumes are bargain-priced - 500+ pages of comics for $16.99 can't be beat. Some fans bemoan the fact that these are black-and-white reprints, but bear in mind that a color volume of similar length would run upwards of $75. Most of these stories have never been reprinted elsewhere, and it's worth a look for the gorgeous Aparo art alone.
