There's one scene of electro particularly just as Spidey enters the powerplant that looks REALLY bad.
That actually legitimately only looks a bit better than the electro from "The Amazing Spider-Man 2" on Ultra settings on PC (If I could replay missions on the game I could prove it but ya'll will just have to believe me)
I loved the Raimi films but the swinging was not as good as TASM/2. The reboot captured Gravity and momentum, captured the elasticity of the web, mad Spiderman himself react to the environement he was creating, as in, he'd fall away to the left or right depending on where he'd put his weight, he'd flip and move through the air naturally, the web allowed natural rigid changes in direction, increases and even decreases in speed. The TASM series had fluid, fast paced, realistic defections of momentum, Gravity and speed.
The Raimi series I did genuinely love and what they achieved a decade ago was nothing short of astonishing, but spider-man does not react to the environment around him; he looks like a second dimension of the scene, as if he's not actually there. He has slight moments of gravity defiance as the stitch the next swing in and I think the biggest thing is he just sorta stays the same. He has no real variation in his day to day swinging. The biggest thing is gravity and momentum however, the Raimi Spiderman just didn't follow it as well, given that the technology was old. An example would be the train sequence, as Spidey flings himself up towards the train, he goes over a building. The direction he went in should have seen him just clip the building but as he reaches it he sorta starts floating up and up before sharply falling down. Another example is the final swing in Spiderman 1 where he is swinging towards the flag. It's as if some magnetic force begins to pull him towards the flagpole. He's up in the air, floating very slowly, and all of a sudden he dips sharply towards the flag. Another thing you can see in pretty much any swing is the delayed transition between the end of one swing and the start of the other, this one is harder to explain in words but he basically sorta jilts a bit, and then jags up before before falling down sharply, and then shoots out a web again and does the exact same action with little variation.
It just didn't have the fidelity and variation of the reboot series. And that just comes down to the current tech. You can say "oh it'll look crap in ten years" but SM1-3 will look even worse as they never captured physics to today's standards, and to be honest I'm not sure how much more accurate the physics engines can get these days, as they're getting more and more accurate. Obviously future films are going to look a hell of a lot better, but I think TASM1-2 will always look more natural then SM1-3
That's not saying that the Raimi series is bad because it really isn't, but both series use CGI in the swings, they're both "cgi fests" if you want to call it that.
At the end of the day, it's folly to claim 10 year old CGI is better then the current stuff.
I understand Spider2099's arguement of the context behind the scenes, but in terms of the raw swings themselves Raimi's are outclassed and that's nothing to be ashamed of
