Good. God. I miss this show. Like Sliders and Spectacular Spiderman, this show will hold a special place in my heart until the day I die. It may seem cheesy to you, but this was one of the many decent examples of good writing, drama, and action in an animated series when I was a kid. Shows like this among Gargoyles, Justice League, Samurai Jack.
Reboot used to come on Cartoon Network. It was a Canadian-animated series that I saw alongside another show called Max Steel (which, ironically enough, has gotten a recent, anime reboot). The show was about the adventures of a group of characters based off of humanized computer programs. The main character, Bob, was a security program "downloaded" or "uploaded" to the city of "Mainframe" which was basically a virtual simulation of what was going on inside of your computer.
Time was regulated to "nano seconds" and jokingly a "second" whenever something was going to take a very long time. The antagonists were two viruses by the names of Megabyte and Hexadecimal; Megabyte was a virus who had a very menacing, yet sophisticated air to him, who sought domination and control over Mainframe and did so by way of very complex plots, whereas Hexadecimal was a super-virus whose power created her very erratic personality - one moment she would want to destroy Mainframe, and the next she was trying to woo Bob into loving her.
The first season was sort of what you'd expected from a children's animated series, very comical, very surreal, yet the animation at the time, so I've read, was very cutting-edge. In fact, when the video game came out, the animation for the cutscenes was identical to the animation used in the show - it was just that good at the time (compare the animation you see in the Naruto anime to what you see in Naruto Ultimate Ninja Storm 3).
The second season is where it got good for those who can't stand regular television shows. Character backgrounds were explored, new characters and threats were introduced, the scale of Megabyte and Hexadecimal's plot grew in their significance, Bob and his friends Dot, Enzo, and Phong were faced with challenge after challenge... and for those who haven't watched the series but are starting to get interested, I won't ruin how Season 2 ends, but I'll say that it changes the scope of the show considerably. Imagine watching Spongebob and then changing the channel over to Battlestar Galactica or Exosquad.
The show went from this intro in Season 1 to this one in Season 3. Yeah, it was a pretty big shift.
Anywho, so Reboot was sort of 'canceled' or 'delayed' after its fourth season, which was after Cartoon Network dropped the show for being too 'dark' (I presume). Instead, the makers found a way to produce the fourth season into two or three movies that allowed them to increase the elements of the show that were previously frowned upon by Cartoon Network. However, the show ended on, gasp...
A cliffhanger that remained famously unresolved even to this day. The fans were so bent by this that petitions were made to have it revived, and lo and behold, the makers of Reboot actually paid attention and started plans to revive the show. They had a website, a comic they used to expand on some of the show's mythology, and there was an announcement of three films that would continue the story from where the show left off. There was even some teaser footage of a redesigned character on the web awhile ago.
That said, nothing, to my knowledge, has come of it since. Most shows I know of that have been out of the spotlight this long are considered dead and buried.
Thank you for taking the time to read all of this and have a nice day.
