Very nice build and nice review Jean-Luc, since it doesn't overlook the numerous shape issues like so many others... You also mention the difficult fit of the clear parts, which many reviewers omit, including Brett Green, despite the poor fit at the front being visible on his finished model...:

I agree that the model's basic research is undoubtedly copied directly from the Monogram kit, the only differences being incomprehensible additional errors, the cowling openings for instance, or here the rear canopy, Monogram being quite correct on the left...:

This should not obscure that the Monogram model is a true abomination, from which the Great Wall kit is a huge improvement, with top quality engraving, good symmetry of components and a great fit for the most part.
Just how badly off is the Monogram kit can be judged here from my canopy smash mould master put on a lenghtened GW fuselage: This is all based on dimensions I got directly from the MAAM restauration (the narrowness of the master is slightly exaggerated by the angle, and the need to undersize the master):

VS the Great Wall:

I will post later a more detailed article on the MAAM P-61 canopy dimensions, and what they imply about the availale 1/48th kits (mostly utter devastation and desolation, unless an entire resin front correction fuselage is offered: The whole front fuselage, nose gear bay, nose gear door and canopies were in real life much longer than in either of the kits!).

I would like address the issue of who I think is responsible for this weird debacle: A top quality kit with mostly very sharply fitting parts (execution-wise), with research and observation that would embarrass a caveman painter of the prehistoric caverns of Lascaux...
I think the culprit is modellers of decades past at least as much as Great Wall themselves (though GW could have got the canopy dimensions from MAAM in less than 24 hours for a modest donation, as I did): Great Wall went mostly with Monogram's great reputation, and theirs is not a bad copy at all: Anybody who thinks the Monogram kit is still anywhere near in the same league as the GW kit has no idea of what they are talking about.
On the other hand, if you think the accuracy of a kit is "sufficient", based mostly on the fact that you won't confuse the resulting P-61 model with a Sunderland, perhaps it would be best to consider that you don't care about accuracy at all, and not try to bolster the reputation of kits that don't deserve it.
I have observed rivet counters rarely get an issue wrong, and even when it does happen, for one reason or another, it merely result in the dismissal of the issue: On the other hand, lavish praise by people who don't care about outline accuracy gets us this: Unwarranted confidence in a model's outlines, and future kits that imitate the previous generation's crap... Not all Monogram kits were deserving of the name's reputation.
The result is that for the next decades almost no one will ever have an accurate 1/48th scale P-61 (including me if I never finish mine, which is very possible), as the amount of work is simply prohibitive:

It's easy to say that some people only talk about the flaws without ever building models, when correcting those flaws is about 20 times the work... The pictures above don't give the slightest concept of the amount of work it took to get there...
I think the Great Wall P-61 kit is probably a good demonstration of what happens when you don't talk harshly enough about a previous kit's flaws, and that is a far worse risk than any miscreance rivet counters supposedly do...
Again, the above review is comparatively a step in the right direction.
