I stuck through the whole series for five years, through the ups and (devastatingly terrible) downs that the 62 book series took. I ran a fan website, wrote tons and tons of fan fiction, and made some of the best friends a girl could ever hope to have, all because of these books.
So even though the books didn't go out on the highest note, I was beyond excited when I heard they were getting re-released, with some small updates to correct mistakes and bring the books into the 21st century. And when Cindy asked me if I wanted to check out the galley copies she had, I about had a heart attack from excitement. I still have all of my original books (including that 14 year old copy of The Visitor...as well as a copy of the second print run version and a copy in German) but I wanted to see what had been changed in these new versions. What I was entirely prepared for was a) the huge wave of nostalgia I felt upon reading the opening lines and b) just how awesome these books still are all these years later! Trust me, there's nothing else like Animorphs out there for this age group right now.
Jake, serious and responsible, quickly slips into the role of the leader of the group. The others all have strongly defined personalities as well: Rachel is fearless, Cassie compassionate, Marco a wiseass with a tragic past, and Tobias is quiet and shy with a good dose of tragedy of his own. Each book is told from a different character's point of view, so these first two give us the deepest looks into Jake and Rachel. If the other characters don't seem the most complex yet, just you wait.
If you thought The Hunger Games was a little too violent...well, Animorphs isn't much better. It's not kids killing kids, but it does involve aliens being eaten alive by other aliens on a semi-regular basis. And Applegate doesn't pull away from these darker scenes - they're not gratuitous, but are certainly well-described.
K.A. Applegate absolutely doesn't condescend to her audience or pull any punches. I know the books end up dealing with some really serious moral issues, including war, murder/killing, the nature of evil and so on, but I'd kind of forgotten how outright violent they start. And I love it. The theme of the whole series is about war and its affects on people (much like the culmination of The Hunger Games), and you can't adequately explore that without getting into some bleak moments. Like I said, the descriptions aren't gratuitous - there isn't a grisly scene just for the sake of being edgy or dark - but they are definitely there, and are part of what really set these books apart (they're intended for ages 8-12...I was 12 when the series started. omg, I'm so old, and always have been in this fandom!).
There are also lots of little bits of awesome commentary that slip into these books. I immediately identified with Rachel back in the day (and she remains one of my favorite literary characters of all time), not only because she was tough and fierce and tall like I wanted to be, but she has lots of feminist moments, taking jabs at the boys when she thinks they are being unreasonably protective. There are also two characters of color - Marco is Hispanic and Cassie African-American. Their races are only mentioned in passing (until time travelling starts happening much later in the series), but it's there. There's also a bit of class consciousness - Marco's dad is extremely messed up after the death of Marco's mother a few years ago, meaning that money is short and they don't live in the greatest of neighborhoods. Meanwhile Rachel is the daughter of divorced parents but has her own credit card. It gets a little bit into Five Token Band territory (warning: TVTropes link), but as their distinct personalities develop it doesn't feel like lazy stereotyping.
For a 15 year old series (I got into the game a year late), it holds up surprisingly well. There's nothing here that screams mid-90s, and as someone who read these books obsessively, I can also tell you that the updating is quite minimal. The biggest update was changing a major continuity error in the first book (well, it wasn't a continuity error then, but they made a big deal out of the opposite thing happening in subsequent books). Otherwise it was like changing the name of a specific game system to just say "system." When I read the new Babysitter's Club prequel last summer, the writing felt like it definitely could have fit in with the original books...which wasn't the greatest thing. Those books were kind of clunky - like the template of the second chapter of every book detailing the characters. Nothing about these books feel dated, other than the fact that they are designed to be a monthly science fiction series - a genre you don't see at the book store too often anymore.
So, to sum up an incredibly long entry, let me just say this: I am so excited to see these books come back so that a whole new generation can get to know these amazing books.
Reviewed from galley copies. The Invasion and The Visitor will be released in May!
