(I hate that I have to make that distinction now)
Weird editing (to the extent it stands out - and I watched the extended edition for goodness sake), tonally all over the shop, far too much badly written cringe humour with overly long verbal gags that go nowhere and add absolutely nothing. Some odd CGI choices (the ghosts are fine, the CGI on people is not), some painful cameos, and a bizarre amount of musical/dance numbers, only one of which is remotely enjoyable to watch or adds anything to the film.
Mixed in with a cast who clearly had fun making it (particularly Hemsworth, who I have never seen ham it up, and he's great at it when he gets into the swing of things later in the film), a fairly enjoyable rehash of the first films plot and some genuinely decent humour when it's allowed to happen.
Basically, this is Feig getting high on himself. Clearly, someone should have told him in several places 'this isn't remotely funny' or 'this stops the film dead and sucks the life out of it for a full three minutes' but no-one did.
Five people dragging Feig away from the directors chair out of Ten. The main cast can do it, they're clearly up for the job, just not with Feig at the helm again, thanks.
