Michael Vazquez’s review published on Letterboxd:
Ah...the nostalgia. I own all these (except for the crappy straight-to-dvd sequels), I love these movies. I still think this one is the best of the series with American Reunion a close second. This one is the best because it hits everything on the head. The characters, humor, story, quotes, romance and music. It's the most balanced movie of the franchise. I LOVE American Pie so much that i've seen it I don't know how many times but I know A LOT.
I don't think there will be a 5th but if they were to make one, I wouldn't mind at all going on another ride with these characters. "Reunion" was the funniest of the lot so I think they have one more in them IF they make a 5th one which they probably won't but hey, anyone can dream, right?
