Can I remove adjectives and adverbs between "so" and "that"?
To find it out, I came up with some sentences:

(1) The movie was so bad that I turned it off.
without "bad":
(1a) The movie was so that I turned it off. — Is (1a) correct?
(1b) The movie was such that I turned it off. — Is (1b) correct?

(2) He sings so badly that no one likes it.
without "badly":
(2a) He sings so that no one likes it. — Is (2a) correct?
