Yo @Ross Scott, I'm real happy for 'ya and imma let you finish, but The Geek Critique already created the best Sonic Heroes review of all time!*
...But in all seriousness, as something of a Sonic Cultist myself (but also a general game player who's played good games in general): In regards to the camera jerking, the automated sections sometimes not working correctly, not being able to judge 3D space in the levels, homing attack not working correctly, that one section in BINGO Highway, the issues pulling the switch in Final Fortress, rail switching not working sometimes, completely falling off a cliff, etc. ... It's not just you not being a Sonic fan or having Gaming Dementia. I can tell you right now: The game is rather glitchy and overall just... kinda sucks. And despite you playing the PC version, these issues were there even on the original console versions; given that I played the Gamecube version wayback as a kid and ran into most of those same problems as well. (I even had to do that exact Tails trick you pulled to get through that final giant laser in Final Fortress.) So you probably should've given this your "Love & Hate" award.
* I'd actually really recommend you watch TGC's reviews/retrospectives on Adventure 1, 2 (Battle), Sonic '06 and Shadow whenever you get the chance, Ross. They kinda give you an idea of what happened during the "Adventure Era" of the Sonic series development-wise.
