This is a review of the quality and coverage of the PDF product. It isn't a review of the content (i.e. the adventures and associated features).
The scan is sloppy. Usually in focus, but often the pages are skewed and there's a bit of bleed-through on pages that had pictures on the reverse of the original page (mainly cosmetic and doesn't affect the functionality) but in some cases the edge of the page is missed, leaving off text - and this happens on several pages, including some giving stats for dragons and PCs - so this product is missing stats on the most important characters. One map is skewed so badly one corner is missed and some of the other edges technically are lost too. The final page, of cut-out paper standee NPC/Monster figures, has the top and bottom row of figures cut off halfway. I haven't checked the colour multi-page maps for missing pages/edges, etc. Might or might not be OK.
Given this is about 80 pages long, it can't have taken much more than 20-30 minutes to scan. Taking an extra minute or two to rescan the skewed and cut-off pages - or even just the cut-off ones - surely falls within the budget of WOTC? Even if they didn't give the job to an unpaid intern? Not even enough quality control to scroll through the PDF and note the cut-off bits before it gets published?
I'm sure an experienced DM could get around the missing information. And you could possibly draw your own figures for the half-missing ones. But for a new DM (which these are aimed at) it could be a blocking factor in playing what they've paid for. And given the source isn't just some random person on the Internet scanning a copy and dumping it on a pirate site, it seems a bit cheap and nasty.
