The original Scooby-Doo shows were famously repetitive. The basic plot structure was identical for every episode, but besides that, they also would repeat the same (crummy) animation sequences. One particular animation sequence, of the whole gang walking from left-to-right, is usually played at least twice per episode. Every possible trick was employed to keep the number of animation frames to a minimum, like when someone crashes into something, we usually see a reaction shot instead of the crash.
Since then, much has changed. Starting in 1998 with Scooby-Doo on Zombie Island, Scooby and the rest of the gang began appearing in a series of direct-to-DVD films. In some cases, the tried-and-true plot formula was followed, but not always. Perhaps more striking, though, was the upgrade in animation quality. The two films made in 2010, Scooby Doo: Camp Scare and Scooby Doo: Abracadabra-Doo, are very well animated. I don't want to oversell this -- don't expect something on par with Disney feature animation. But when you consider where the series started, it's an amazing transformation. In these two films, characters are shadowed and shaded, richly animated, travel freely in three dimensions, and I spot lots of computer-assist, like lens flares on flashlights in the dark. I honestly haven't been this impressed by t.v.-grade animation since the original Batman: The Animated Series. What's also great is that although the quality of the animation is updated, the characters have their classic look and feel. I can imagine the temptation was great to modernize the look, but that's been wisely avoided.
Okay, so the films look great, but what about the rest of it? Both of these films have good stories. I mean, let's face it, in the end we are still talking about Scooby Doo, and it's foolish to expect a plot worthy of G. K. Chesterton. All of the films in this series suffer from a basic problem, namely that some guy wearing a mask scaring people for nefarious ends really isn't enough of a story to fill out a 90 minute film. Some of the films handled this problem badly, namely by adding truly supernatural elements or idiotic subplots. But Camp Scare and Abracadabra-Doo come by their lengths honestly, by letting events unfold gradually, and allowing little character moments to fill in time. My only plot complaint is that the villain of Abracadabra-Doo is apparently motivated by the desire to make a little cash, which is fine, but is employing a scheme that looks like it would cost millions of dollars to implement. It's like a guy trying to transmute gold back to lead or something.
The characters are fun, with more depth than you might expect from the old show. Fred in particular has blossomed from the leader who never missed an opportunity to split the group up, to an over-eager, sweet-hearted goof. In Camp Scare, there's a running gag about Fred wanting to be a great counselor at the camp he attended as a boy, and gosh if I didn't almost start to care a little about Fred before I came to my senses and remembered I was watching a Scooby-Doo movie. And while Shaggy and Scooby are always the most annoying elements of any Scooby-Doo story, there are moments in Abracadabra-Doo where the pair are downright heroic.
Some notes on the casting: Casey Kasem has retired, and Matthew Lilliard, from the live-action Scooby films, has taken over voice duties for Shaggy. Although he has the vocal tics down, he doesn't really sound anything like Kasem. It's just something you have to accept. Also, Velma is now voiced by Mindy Cohn, best known as Natalie from The Facts of Life. It turns out to be a great fit. I was surprised--other than using Velma's trademark vocabulary ("Jinkies!"), she uses her normal voice, and she doesn't really sound like the original Velma. Even so, she sounds very natural for the character.
Rating for both films: 3/4. Bottom line: these two films are about as good as Scooby-Doo can get. They are still too much of a formula children's adventure to be worthy of the fourth star, as I can't imagine sitting through an entire 90 minute Scooby film without my daughter on the couch next to me. But for what they're aiming to be, they hit the mark. Bravo, Scooby! Have yourself a scooby-snack.
