Stylistically, the characters' blockier animation may take some getting used to, but the technique works well in setting this new series apart from earlier iterations. Beyond the character design, there is also a noticeable anime influence in many of the turtles' expressions – especially those where the scene plays up this series' more humorous, child-friendly tone. Most telling, however, is the way each turtle has identifiable markings or features that set them apart from the others. Gone are the days when the only distinguishable aspect was the color of the bandana, choice of weapon or voice. Here, each turtle has a particular facial or body feature that offers a nice, subtle variation on each of the teenaged warriors, and helps them feel more like a distinct character.

The training clip clearly shows that Splinter (Hoon Lee) has been updated. He appears to be much younger than he was in the '90s cartoon – likely allowing for him to engage in more fisticuffs alongside the four turtles. While the trailer and clips are lacking glimpses of key villains – though we see plenty of stock bad guys playing up the "mutant" angle – there is a pretty decent shot of the new Shredder (who is basically the same, but with a damaged right eye).

As with any other changes, the new theme song will probably have plenty of detractors. While it's no less cheesy (yet enjoyable) than the original series' intro, it does feel humorously out of touch with what might actually appeal to the key demographic. Listening to the theme, one can practically envision television producers snapping their fingers in time with the rhythm and using terms like "hip" and "fresh" to describe the updated song.

That being said, the new Teenage Mutant Ninja Turtles looks like it will have plenty to offer young children and older fans of the nearly 30-year-old franchise.
