After having some issues around spaces and format I decided to try a basic approach, so I wrote an easy to read script. It may not be the most optimal but it does the job and is easy to maintain.

So, the code joins lines into one (so that they all start with R| ). Then performs some sentiment analysis on the line and appens |positive |negative or |neutral at the end
Code:
BEGIN {
        FS = "|"
        OFS = "|"
        IGNORECASE = 1
}
{
  full_line = $0
  eof = 1
  while (eof > 0) {
        eof = getline next_line
        if (eof <= 0)
        {
                sentiment(full_line)
        } else if (next_line !~ /^R\|/)
        {
          if ((full_line ~ / $/) || (next_line ~ /^ /)) {
                full_line = full_line next_line
          } else {
                full_line = full_line " " next_line
          }
        } else if (next_line ~ /^R\|/)
        {
                sentiment(full_line)
                full_line = next_line
        }
  }

}

function sentiment(LINE) {
        if (match(LINE, /(no[t]*|wasn[']*t|isn[']*t|ain[']*t) (that |very )*\y(good|great|best|excellent|brilliant|amazing|magificient|fantastic)\y/))
        {
                print LINE, "negative"
        }
        else if (match(LINE, /\y(shit|crap|awful|worst|stupid|idiotic|arsehole|bastard|shite|disgusting|nightmare|hate|hated|angry)(s)*\y/))
        {
                print LINE, "negative"
        }
        else if (match(LINE, /\y(good|great|best|positive|excellent|brilliant|amazing|magificient|fantastic)\y/))
        {
                print LINE, "positive"
        }
        else
        {
                print LINE, "neutral"
        }

}
