The first four seasons were a rollicking good tale and good fun to watch. Full of space opera adventures and intrigues. This series however seems to meander through with bizarre plot lines and and dangling threads. It seems, to me anyway, that the crew knew it was the last series and wanted to have some fun as they all seem to be enjoying them selves. On the whole, not the best as far as sf goes and a bit of a disappointment after the first four seasons.
