As said in my previous 'Scooby Doo Where are You' reviews, 'Scooby Doo Where are You' still holds up as the best of the numerous incarnations of the immensely popular franchise, of which "Which Witch is Which" is one of my favourites.
The swamp setting is incredibly atmospheric, with the colours and level of detail gone into it it is up there as one of the creepiest settings on the show. "Which Witch is Which" is also advantaged by agreed two great villains that add hugely to the episode's appeal. The witch is very well designed and effectively menacing, but the zombie is even more memorable, the design is freaky but he is so much fun. The identity of the perpetrator is not really that much of a surprise, but to be honest there are far more obvious reveals and often with villains not as interesting.
Like with the best of Scooby Doo, it isn't just the atmosphere and creepiness that makes "Which Witch is Witch" so worthwhile. 'Scooby Doo Where Are You' is always high in the fun factor, and "Which Witch is Which" has fun in bucket-loads, with Shaggy's witch impersonation, the Jelly Beans gag and card game being the funniest gags and also three of the entire show's funniest moments. The dialogue is vintage Scooby Doo, with the best lines coming from Shaggy.
The story has continuous energy and atmosphere, and is never confusing or too obvious, and the final trap is creative enough.
Shaggy and Scooby never fail to bring a smile to my face, likewise with their ceaselessly charming chemistry, and Fred, Velma and Daphne are no less enjoyable either. As always, Don Messick, Casey Kasem and Frank Welker stand out of the voice acting, Messick and Kasem are without equal as Scooby and Shaggy and one cannot believe that it's been nearly 50 years and Welker's still voicing Fred with no signs of fatigue or inconsistency.
The animation is lively, atmospheric, lushly coloured and nicely drawn as always. The music adds to the impact the atmosphere creates, and it is very difficult to resist the classic theme song, along with the opening credits where it is so fun spotting and recognising the villains, that is one of the most iconic in animation.
All in all, wonderful episode and always has been a personal favourite. 10/10 Bethany Cox
