There's no faulting the content of this DVD, even if our household do prefer the original episode format (this is the first series made in the computer enhanced, longer episode format with the "Engine Roll Call" theme song).
The reason I've marked it down is because of the mess Hit have made of the presentation.
One star is lost because of the trailers at the start of the DVD, which can't be skipped. This is an inexcusable liberty (it takes long enough to load up as it is), which thankfully wasn't taken with the previous series 1-7.
The second star is lost because of the fact that you have to sit through the entire introduction and extended theme tunes at the start and end of every episode, whether you choose to "play all" or "select an episode". This gets tedious very quickly.
My advice to Hit for series 9 is simple: Drop the trailers, and instead include the introduction ("Welcome to the island of Sodor", "Who's that puffing down the track?" etc.) just once, before the options screen. Then start and end each episode with a cut down version of the theme tune.
If these mistakes were corrected I would have given it 5 stars.
