Could you explain why you think you're in a good position? From what I understand, the comments are owned by the users, and by posting them to IMDb, they allowed IMDb and their affiliates the right to use them.
The users did not give you permission to use their data, and you're not associated with IMDb, and therefore do not inherit the rights.
Lastly, IMDb specifically states that scraping or extracting data is forbidden without written consent.
