I think we get too hung up on terminology. If you enjoy watching a movie over and over, that's a great movie in my book. It's 100% about a movie's ambitions and whether it actually meets them. Kinda like Olympic diving. The difficulty of the dive matters, but a great dive is a great dive regardless.
Even formulaic movies (and comedies in general) can be great. That there are a bunch of shitty "fish out of water" comedies doesn't make My Cousin Vinny any less great. The litany of underdog sports comedies that suck -- even their own sequels -- don't hurt the greatness of the original Bad News Bears or Major League.
Another factor is the whole idea of a "guilty pleasure," which I've always thought is silly. Like what you like. Why be embarrassed about it? So we can love watching Happy Gilmore, but we can't say it's a great movie? Screw that. It's trying to be a funny movie and succeeds. The ambition may not be very high, but it clears the bar with ease regardless. It's a great comedy.
"But it's no Citizen Kane!"
Why is that the metric? What's the point in comparing a great sports comedy to a great film from another genre? Compare it to great movies of its ilk. Does it hold up? Yes? Then it's great. What's a comedy masterpiece for you? It's subjective, but pick one that sets a high bar and compare Happy Gilmore to that. For me, Young Frankenstein is an all-time great comedy. It has layers of satire and parody that add deeper value, but it's a comedy nonetheless. The best thing I can say about any comedy is that I laughed throughout, and that's pretty equally true with both movies. Both are great. Equally great? Who gives a damn?
As for Doctor Strange, it was fine. My problem with the MCU now is the time travel and alternate universes. If you use those ideas very sparingly and only ever in clever ways, they can be great, powerful tools for telling interesting stories. But that almost never happens with either concept. Eventually they're allowed to run away with themselves until the universe you've created is now completely devoid of consequence.
And that's where the MCU is now. The original Doctor Strange's ending is a perfect example. The whole story builds to this impossibly huge climax, and it just gets undone over and over until he figures out how to win. The only saving graces are that A) he puts the Time Stone away, never to be used again (wink wink). And B) the self-awareness of that moment -- i.e. "It's time travel, stupid. I can keep doing this over and over and over until you just plain get sick of it." It's easy to enjoy that particular ending done that way because it's understood that it's something of a one-off. But then Ant-Man 2 and Endgame and Loki and No Way Home and another Doc Strange...
Now we're at the point that they're doing it over and over until we're just plain sick of it.
Consequence is important. Nothing means anything if everything can be undone. (Say THAT five times fast.)
"Oh no! (SPOILER) is dead!"
Yeah, but they're not. We just saw 14 alternate versions of them, any of whom can come for a visit whenever we need them. And if you're really stuck on that particular one, then just go back in time and save them. Easy peasy.
So I wouldn't be upset if we never saw that multiverse girl again, but given that they've just introduced younger versions of damn near every Avenger (Hawkeye, Black Widow, Captain America, Ant-Man, Ms. Marvel) with apparently more on the way (Hulk, Iron Man maybe twice, Black Panther, etc.), I'm not holding my breath.
