The rest of Beware the Batman season 1 aired on Toonami (during bat hours Saturday nights on Adult Swim) and I'm really getting into it. Here is why The Bat thinks it's a solid series.
7. Alfred is bad-ass
Like a CGI Jason Statham with Acromegaly.
6. Lesser featured characters
Tatsu Yamashiro/Katana is sort of the answer to a non morally ambiguous Selina Kyle/Catwoman, Lady Shiva to Talia al Ghul, and Anarky is . . . creepy.
5. Batman is a true detective
More Denny O'Neil influence, which I prefer over the Frank Miller-inspired animated movies.
4. Character development
BTB has more of a chronology compared to Batman: The Animated Series -- more time spent fleshing out each hero/anti-hero/villain.
3. Barbara Gordon, aka 'Oracle'
Oh, she is just so cool! Kind of serves as the 'Robin' in this series; in other words, saves the day when Bats is in deep stuff.
2. Good mix of villains and action
Okay, some episodes are admittedly dull (even BTAS had its share). I don't know if it's ending with season one, but I can see things escalating in Gotham City -- this is a young Batman, and Batman creates villains. A couple villains I think would start to fit in this universe are Riddler/Nigma and later on, Bane (do it like the New 52 Bane) -- because eventually Batman needs to be tested mentally and physically. Of course, no Dark Knight universe is complete without The Joker, but one can dream . . .
1. Batman
Beware the Bat does the difficult task of highlighting the caped crusader instead of his flashy villains. It's a good Bruce Wayne and Batman story. It's not voiced by Kevin Conroy, and it doesn't need to be.
Beware the Batman does have most of its scenes at night (even for a Batman show); which was probably one of the reasons it didn't perform well as a Saturday morning cartoon. On the other hand, The Bat happens to be a very big fan of the theme song.
