Since every coin has two sides so there may be some areas which needs to be improved where sentimental analysis fails  such as Name Entity Recognition, Anaphora Resolution, Parsing and Sarcasm. Think about those text which are misspelled or written in short letters or abbreviations and are grammatically incorrect. I personally find such in social media sites (Facebook or twitter). So such points needs to be considered and sentimental analysis field has to overcome such areas.
