Now, don't get me wrong: It's heyday was, strictly speaking, the Chuunin exam. The forest of death had some cool shit in it: More than one special-animation-team fight, giant monsters, the one guy who says "Lucky!", etc. And the obligatory shounen tournament arc that followed, lifted directly from DBZ or Yu Yu Hakusho, had some well animated/cool fights also. And, I guess that frog summoning bit was cool when he managed to summon the big boss frog and then passed out. There was about 20 episodes of good shit in the Chuunin exam.
The problem, of course, is that the exam lasted nearly 50 episodes, and you had to wait through nearly 15 hours of bullshit to get to the 10 hours of good stuff. Like, remember that written exam? Five episodes of "oh noes, i dint' study!!" right there. Like anyone needs to see that.
By contrast, the first 20 episodes of the show are good without being interrupted by gay shit, ending in the Zabuza/Haku speacial team fight. There's a bit of "I just attacked you, and now let me explain how it worked!", but that was forgivable. There's not a whole lot of reason to keep watching, though.
