Absolutely not because it wasn't a very good adaptation.
I've actually spent the last few weeks re-watching numerous Guyver clips (gotta stay interested somehow!), mostly of scenes that have been adapted numerous times into anime and the 2005 series ALWAYS misses the mark.
I can't actually be bothered to watch the whole of the first episode of the 2005 series but I watched the key scenes earlier this week and while, yes it's well drawn (most of the time), everything lacks punch and emphasis. The changes to the manga don't offer anything positive to the narrative or watching experience. Turning the truck driver into two police men makes for a fess interesting situation, and even though the driver was an asshole in the manga you could at least relate to the fact that he was just a guy in the wrong place at the wrong time. Making Malmot a family man was also completely uninteresting because it wasn't developed - why should the viewer care about this guy when all they've seen from him is the murdering of the two police men? He was more pitiful in the 12-part OVA just by having him talk to Agito on the phone at the beginning of the episode.
Malmot's transformation is done okay, and he's actually drawn extremely well, but Gregole's transformation lacks any emphasis. It looks like they just didn't want to go through the effort of making it more dramatic so they have him transform far from the camera so they could skimp on the details of it. Same thing goes for their fight - I can only imagine they didn't want to go through the effort of animating the arm wrestling match so instead we get... basically nothing before Malmot blows himself up. Out of Control's fight on the other hand is unbelievably well animated for something that came out 30 years ago. Removing the arm wrestle completely ruins the setup for the wrestle with the Guyver; the power scale from Malmot - Gregole - Guyver is less evident.
Sho bonding with the unit is slow and lacks the dynamism it had in the 12-part OVA. The fight with Gregole looks amazing and thank goodness they kept the arm wrestle this time but what is with Gregole aiming his punch to the side of the Guyver's head? I imagine it's supposed to represent the Guyver dodging the punch but he doesn't move at all. And the finish of the fight also makes me feel like, once again, they just couldn't be bothered to animate the Guyver's last attack, so creating that moment of suspense was the easy way out. I appreciate it must be an absolute nightmare animating Guyvers and Zoanoids but if they got it right 30 years ago pre-digital animation then there's absolutely no reason they shouldn't be able to do it now. If the budget was too tight then they may as well have not done it at all. Maybe it's just one of those series that needs that 80s/90s anime grit to work.
The English voice acting is also pretty bad - the delivery is often flat and the quality difference between the JP and ENG acting gets pretty bad in some parts of the series. (For the record I'm not always opposed to english voice acting - FMA has a great dub). But this is a more general criticism rather than being directed to the first episode specifically.
That said, I disagree with you Maze on the soundtrack. It's not as good as the 12-part, but it's still pretty cool.
I like the idea of this thread, I might play along for a little while but it's hard to stay entertained while watching this series. I would never recommend it to anyone wanting to get into Guyver - at least not until the last few episodes.
