Conversely, when it first came out, I thought TUC was a top film in the franchise...and it's fallen massively since then due to it's very obvious flaws (rushed production, flawed story elements, wink-at-the-audience performances).
I found the same thing. When it came out I loved it. Definitely was a top 3 at the time (of course at that time there were just 6 films). And it sort of stayed there for several years, though First Contact eventually took it's place at #3 for me.
But it hasn't aged well for me. It's become a middle of the road film IMO. I don't hate it, it has it's good moments and the ending was a perfect send off for the original crew. That alone made up for some of the flaws. And I'll admit, as caricatured as Chang was, I can't help but like him. Probably because Plummer is such a great actor, and, well the patch nailed to his head was very Klingon

For me, it's all relative. I honestly don't think the TNG films were "bad" in the broader context. I just think they are weaker than the TOS and Kelvin films. I actually enjoy all of them to varying degrees, and for the most part I believe they are entertaining and competently made. They may not have worked well in the context of the franchise, but I think they are solid sci-fi action/adventure movies in their own right.
I thought they were decent enough. Insurrection was definitely the weakest for me, and if the special effects for TFF were ever 'fixed' I can replace that with Insurrection as my #13 movie. I didn't hate Insurrection, I can still watch it today from time to time. It was competently made, had some great photography, and the special effects, while not awe inspiring, were at least in line with most of the other films. The story just didn't take a lot of risks. They wanted to do what TVH did after TWOK and TSFS, have something light-hearted and maybe a bit comical after the headier FC. But I just kept thinking to myself the Dominion War was still raging at that point in time on DS9. Why was all this even going on, and the Enterprise was originally supposed to be going on an archaeological dig. Um, during a war to save the Alpha Quadrant? I always thought they missed an opportunity there. I realize they didn't want to make a movie that required the general public to be familiar with what was going on DS9 at the time. But I still think there could have been ways to incorporate Insurrection into the war somehow without requiring a familiarity with DS9. And I mean, come on, who didn't want to see the Enterprise-E engaged in a battle with a Jem'Hadar warship at least once?

And of course we're one of the 10 people that liked Nemesis
