overall worth seeing; but I think the movie that the built in audience would have liked to have seen was all the adventures Indy was describing about working with the OSS in WWII. There's way too much science fiction interdimensional hoo-haw in this movie- and all justified by Lucas saying that unlike the 1930's serials; this one is based on the 1950's sci fi's. Uh ok. But this is IJ!!!! And lead doesn't let radiation in btw, but it does melt....
