I've bought Lepin's Black Pearl and must say the quality is pretty good, though the sails are plasticky but I leave that for anyone to easily modify. Minifigures are pretty good, though Davy Jones is of a different shade of blue. I'm targeting the Grand Carousel and Emerald Night next as the original sets are grossly overpriced on the second hand market. I've bricklinked the UCS Falcon before and own or BL some of the modulars, so Lepin sets are "filler" of sorts. :P
I guess Hollywood has run out of creativity? After all, it's either a comic book or novel/story book adaptization to movies nowadays, e.g. Marvel/DC, Harry Potter series, Twilight saga, Percy Jackson, LOTR/Hobbit, etc.
