Waynes World I and II - I'm with you. I love the first one too and the 2nd one quite a bit as well, because I remember seeing it possibly even MORE back in the day than the first one. I haven't seen these in a long time but I'm sure I'd still enjoy these and I also have a lot of nostalgia for these too.
Coneheads - This one seems alright. I think I had it on recently but never really sat down and actually watched it. It was usually on in background. Seems like an average early 90s comedy overall. Lot of cameos from what I remember which did make it interesting to check out.
Its Pat - Wasnt Ween in this movie? That is an interesting tidbit about Tarantino. I totally forgot Julia Sweeney was in Pulp Fiction towards the end. I remember her looking pretty hot in that movie too. Def don't remember much about Its Pat. I do remember Charles Rocket was the "villain", a guy trying to prove Pats gender or something and some more cameos of other SNL people or comedians.
Stuart - I think this was on HBO briefly too in the mid 90s. I remember the SNL sketch more than the movie. Never cared for this character but I get it. Its a decent parody of those kind of "inspirational" tv shows with some wholesome guy or woman who tries to help people.
Blues Bros 2000 - Yeah seems pretty notoriously bad these days. Never saw it as far as I know. Thats funny you saw it with your mom. I saw the Psycho remake in the theater with my mom. The part with Vince Vaughn looking through the peephole jerking off was one of the most awkward moments of my life.
Night At Roxbury - This was on TV a few years ago and saw some of it. I guess it was decent how they managed to make an actual movie on this. I wouldn't willingly seek this out on my own but it wasn't a terrible abomination I guess. It was a decent comedy, though stupid.
Superstar - I remember when this came out, didn't care for the character. This is when SNL started going really downhill for me, the late 90s era. Even though Will Ferrell and a few others were good
never saw Ladies Man or Macgruber. MAYBE i'd check them out if really bored. I have no idea how Macgruber managed to get made and I always appreciated Tim Meadows, so I guess its not bad he got his own movie. I'm sure it was a total flop though.
I grew up with those Adam Sandler and Chris Farley movies. I have some nostalgia for them. I guess Billy Madson might be still stupidly funny. Big Daddy was pretty decent when i saw some of it recently. I honestly think Sandler can be a really good actor in a few of those drama movies he did. I'll always appreciate Airheads, which is basically a rip off of Dog Day Afternoon!
