Yes it's short time-wise, but my god listen to what you get!! I've never been a fan of the "we've got 70 plus minutes to fill on this here cd, so put everything available on regardless of quality" etc school of thought. For me, the old vinyl lp standard of 35 minutes overall (about 18 min per side) was always a perfect constraint with which an artist can do their thing (exceptions being some double lp sets, ie the White Album, Physical Graffiti, Exile On Main Street).
In any event, if you like George's work you'll LOVE this set, and for complainers who cry 'rip off', I would just point out how Olivia Harrison did NOT do what most major rock figures routinely do, which is to make these "bonus" or "extras/out-takes" sets available ONLY if you buy them as part of an uber-pricey super-deluxe boxes costing hundreds. Instead, you only have to drop a tenner.
And if you LOVE George's work, well you've already bought this haven't you?
