All of the series
 

So, I'm a fan of the TMNT movies, the 80s series, the old comics, and the 2003 cartoon series. From what I've seen, this new TV series seems to be a grab-bag of elements from pretty much every Turtles series.
So, my question is this:
Is the new Ninja Turtles series worth viewing?

Hell yeah. It's the best animated version of them to date.

Yeah, it's definitely worth watching. It's great.

I won't say its the best version, since there's things the previous cartoons do slightly better (and slightly worse), but its a very good show especially considering what it could have been.

If you like Turtles, watch it.

God yes. Well, that's just my opinion - but, yes. :)

Not going to please everyone, but its tone is a nice middle point between the prior two series. And it's fun that the Turtles actually do seem young for once as claimed. I wasn't sure about it at first, but it quickly grew on me. (Edit: Actually, it has the credit of bringing me back to TMNT after being away from it for so long.)

Same here

Very good series that hits a good mid point between comedy and action/horror. If it had any specific consistent flaw, its that its often too short to properly explore the ideas it brings up.

My preference is still the 2k3 series but this is a pretty well done show and yes it does contain elements from different parts of turtle lore.

I would describe the Nick series as watchable.

I personally rank the three cartoons as:

1. The 4Kids series
2. The original cartoon
3. The Nickelodeon series

Hell yes it's worth viewing! I love it, and I would definitely recommend it to anyone who wants to give it a shot. It may not please everyone with certain elements of it, but I'm a huge fan of it.

I agree with this 100%. Also this did bring be back to the turtles fandom.

Totally watch it. I didn't at first because I thought it would be too childish, but it is much more than that. Even though 2k3 has many amazing episodes, the Nick show is my favorite TMNT series.

Definitely.

Definitely worth watching!

I think I'd still give 2K3 the edge as my favourite series but Nick is damn close! I'd say 2K3 had better plotting and pacing but Nick has better characterisation.

Took the words out of my mouth.

It's certainly the best looking of the TMNT 'toons.
The stories vary in quality, but even the "less good" ones are still better than average.

If you've got the time, and of course the means, give them a go.
Then come back and tell us what you thought.

I actually made a DeviantArt Journal about this whole subject based on Season 1 http://fav.me/d99slyu , but here's a nutshell:

Probably yes. It's a great series for at least the first 2 seasons. I personally feel Season 3 had ups and downs, but it still is worth watching.

Yes it is very good. 2003 series is more serious but Nick series is the best action adventure cartoon show now. If you liked the 87 and the 2003 series you will also like it

Heck to the yes. It's a well-written show, but like all things it has it's ups and downs.

Depends on what you like I guess. :)

I personally believe that the show is good, just it struggles with story and some balance of characters at times. Just be wary of season 3 though, tons of issues in it in my opinion. However, I can say it is one of the best versions of the cartoons, tie between this and 2k3 as the best in the franchise.

Feel free to tell what you like of the show.
