This is my childhood memories right here. Even till this day this series is a timeless classic. I'm a sucker for Time pieces,(stuff that take place in the 30s,40s, etc.) this series is a mixture of both modern and 40s era just like the movie Batman (the 1989 movie) in which I'm also fan of. The first three seasons animation is superb I seen nothing like it back in the early 90s and nothing (America animation) is as beautifully drawn like it since that time. The Theme in which it borrows heavily from the 89 Batman theme but made it it's own of all Batman theme's this is still the best theme to define this character. The forth season is good however I'm not a fan of how they changed up the animation in that one. When I see the 4th season, one of my main complaints off hand is how lazy the design of the Joker is in the 4th season and Poison Ivy design were disappointing she was much sexier in the original animation. However even with that they make up for it with faster action sequences and they used the same animation style in Superman adventures and Justice League cartoons so it became the norm for the rest of it's continuity. Bottom line If you are a fan of Batman you should own this series but be prepared for a animation face lift when you get to the fourth season.
