I think that the original Star Wars trilogy is a great example of something being "too perfect for its own good." Sure, the films have their flaws, but, that didn't really stop an entire generation (and several after that!) from experiencing them. Many future filmmakers and TV producers were heavily inspired by just how special Star Wars was to them... Many decided to parody or reference events from the film as tribute and homage in the years since.
However, that almost ruined it for someone like me. Just think... really, just stop and think right now: how many times has Luke Skywalker's parenthood twist been parodied or referenced in other media? Really, actually think about that.
I can't think of many specific examples right now, but, I know that we've all seen/heard them. Even if you lived under a rock you'd still know the basics of the original trilogy's plot. Just as one example: I saw Chicken Little (2005) about a year or two before I'd ever seen Empire, but that didn't stop the filmmakers from alluding to the pivotal plot twist anyway.
Sure, I really like the Star Wars films (all of 'em), but, I think it'd be hard to find someone other than original theater-goers who wouldn't already have bits spoiled for them before they ever watched a single one.
Guardians of the Galaxy, in a totally different way, could be classified as "too good" from me as well. Don't get me wrong, I hate the film - utterly despise every frame of its existence - mostly because it was the first Marvel film (actually, first film ever) that I had seen where the MPAA rating and stylistic choices seemed formulaic to its success.

Write a bland but action packed script with subtle fan-service here and there, rely on CGI for explosions and some extras in crowd scenes, throw in a few swears to make sure the film isn't PG (because, really... who watches PG anymore, right?), color grade everything a shade or two grayer than reality to look "modern", use a temp score, and end with a "hey, please stay and watch the credits - not to honor/learn of the people who dedicated their time to making this piece of entertainment, but just to see sequel bait and a pointless cameo."
Most of the points made in the above paragraph are common criticisms of modern blockbuster cinema (think Michael Bay) or of the MCU in general... but, it had never seemed so bad before. Sure, Vertigo's bold Technicolor blows The Avengers dull blueish hues out of the water, but Avengers actually was pretty entertaining for me at the time... after credits sequences and all. The formula may have been in place, but the filmmakers still put the film first... instead of just appealing to the lowest common denominator.
Guardians of the Galaxy, in my opinion, succeeded at every field the filmmakers tried to tackle - it's just that those fields are all major negative trends in mainstream cinema...
When it comes to brickfilms, the same thing applies. I sometimes find myself slightly disliking a brickfilm just due to its "flawless" animation... especially when other fields (such as audio or story, for example) are underdeveloped... Sometimes (in brickfilms and theater cinema) playing things too safely can really hurt the artistic integrity of the final product.
To err is human, am I right? I think that a little bit of flaws can go a long way - severe creative limitations, especially, sometimes lead to creatively original ways to overcome weaknesses. That's why I'd choose to watch Doug Vandegrift's Pirates! first, over Smeagol's Unrenewable - Not because I prefer pirates to neo-noirs, but, because Pirates! is just a bit more entertaining to me. I've learned to love its flaws, and that makes it just a bit more special to me.
