Oh it's correct alright. I haunt other sections of t'internet and droves of people who went to see LotR aren't all that bothered about The Hobbit, if in fact they're bothered at all. Many of these weren't all that bothered about LotR but went to see it anyway - that's marketing for you. People are soon bored. Not us, but
them...the
other ones...
Star Wars is interesting because if you wanted to follow the story of what happened, going to see the films was the only way to find that out! Of course this doesn't happen with films based on blockbuster books.
