If you've been around since the original Jackass series and love watching these guys for their personalities and chemistry, then you will probably enjoy this as much as I did.
If you do not care about the guys, their history or chemistry, but rather just watch some dudes do silly stunts, then 4.0 will probably be more of your cup of tea.
Jackass 4.0 was all high budget, polished stunts with little talk. Giving you less insight into the chemistry between the guys, and being less intimate.
4.5 is more intimate, focusing on the pranks they pull on each other behind the scenes and watching them having a blast together on low budget stunts. Which feels in a way more pure and true to what made Jackass great back in the days; a bunch of guys with zero to no budget and a video camera, doing silly stuff.
On top of that, they have behind the scenes/set talk, with the guys talking about their experiences and thoughts. How ideas came to be, how the movie came to be, the issues they encountered, backstory of the new guys and why they were picked, their very first stunt together and everything in-between.
For me personally, as a longtime fan of the guys themselves, this was way more intriguing and in a way nostalgic to watch, rather than just the high budget stunts of Jackass Forever.
In a perfect world, I'd like to see a 3 hour supercut mix of 4.0 and 4.5, as they are both good in their own different way and give out slightly different vibes, where one is more "grand", a bit more shallow and suitable for new audience, while the other is more intimate/deep for those who enjoy that.
I feel like it gave me somewhat of a closure to the original Jackass guys, and a welcoming to the new guys. A smart transition to the upcoming Jackass series reboot, which will probably mainly (if not only) feature the new crew.
