the film so woundfui. we are all excited.对吗

the film is so wonderful, we are all excited

the film is so wonderful. (要有动词is)(注意wonderful的拼写)
we are all excited.对

不对
the film is so wonderful that we are all excited.

the film is so wonderful, all of us are excited.

不对的，缺少谓语，film后加looks,应该是woundful。

如果是口语，省略掉"is"是没什么问题的。如果是正式的书面表达，"is"就不应该被省略。
