This animated reworking of the Spidey mythos is fresh and exhilarating in a way that very few of its live-action counterparts have been. 

【翻译】这部蜘蛛侠神话的动画翻拍令人耳目一新和振奋，（其方式）是很少有真人电影能够做到的。

1. 表“方式” 的way 之后接定语从句，用 that, in which 或者直接省略关系词，已为常态。例如，以下两组句子，3种表达都可以：

2. 在定语从句中，have been 之后承前省略了表语fresh and exhilarating。

3. many, much, few, little 这4个词，既是表“数量”的限定词，又可以用作不定代词。由于做数量限定词时可以用程度副词very,too 等修饰以及有比较级，所以用作不定代词也保留了这些语法特征：仍然可以用程度副词very,too 等修饰，以及有比较级形式。

very few of ...中的few 是不定代词，可以用very 修饰。

This animated reworking of the Spidey mythos is fresh and exhilarating in a way that very few of its live-action counterparts have been.

解答如下：

(1)that very few of its live-action counterparts have been.是定语从句修饰前面名词“way”关系代词that在定语从句作表语。

(2)few为形容词，very为副词，副词very修饰形容词few。
