Great movie! There are NO analogues of such a movie! I watched it for the first time in 1999 at my friend's house! We with him were in full delight.
I advise you to watch after this movie "In Pursuit of the Emmy" - comedy, but more serious and in some places even on the tear pierces, then "Jay and Silent Bob strikes back" - this movie is also funny, but already "on the modern way" ....
And also, who before "Mallrats" didn't watch "Clerks", I advise you to watch it, to understand "Clerks" you may even have to watch it several times - a masterpiece, despite the fact that it is Kevin Smith's first movie. The most interesting thing about these movies is still that each of them mentions one or another of the characters that were in the previous or subsequent movies. In short, you won't lose any time!
The main thing, do not try to look for flaws: "Mol, stupid American humor!" The trick in this humor is not in phrases, as in Russian humor, but in life situations!
Thank you for your attention. I wish you all the best.
