The Film flopped because of bad luck with the timing and no advertisement for it.
The Pirate thing was not popular at the time also strong female leads weren't as big as they are today.
It is no worse than any other action film. It is just as good as some of the best Pirate films.
They spoke colloquially in it had decent costumes, it all was done as real as possible with very little CGI.
Was it a tad cheesy? Yes but all action films are.
Was it an adventurous Swashbuckler? Yes I feel it was.
I watched this at first at a young age on TV so I had no idea it was a huge flop. I got to see it without any preconceived notions and just enjoyed it for what it was. I just recently heard about it being a flop and was really surprised by that. I just saw it again today I feel the only thing I thought it needed was some editing down to make it a bit shorter and the soundtrack could have been stronger. Its a fun film to watch with kids. Nothing wrong with that IMHO.
Im not saying its the best film ever but it certainly isn't the worst. If you like Pirate movies give it a go don't just listen to the critics.
