AndrewC: Yes, but the only problem with that is that the game never set up to do anything new, nor the original nor this remake.
The original was just going back to the roots of FPS gaming: fast action, lots of monsters to kill and had a wicked good co-op multiplayer because of this. It never wanted to bring new mechanics and engage the player in an amazing story. It was just about mowing through hordes and hordes of baddies.
The remake was just the first game with better graphics; to say that you wanted more when the devs stated first-hand that nothing except the engine will change is stupid. That's the problem I have with articles that involve grading a game, it can never cover the experience a player has while gaming nor does it mold on what the game tries to be (in this case an old-style shooter).
Also, Painkiller was made with the same mechanic in mind and did very well. Heck, even Doom 3 did it.
It's the same as players screaming that StarCraft 2 is almost the same gameplay wise as the first one despite newer mechanics as squad play and capture points instead of resource mining; well, duh, it could use all of those but it wouldn't be StarCraft now would it?
In the end, if you want a relaxing session of mindlessly blowing up enemies you grab this or any other game in the same fashion.
Painkiller had more "flair" and shinier guns. Plus, it came out a few years before the Serious Sam remake :p
DOOM 3 was called 'DOOM", do the math
Starcraft 2 is called "Starcraft", do the math :p
Seriously though. Most budget games aren't made to be blockbusters, but they tend to get atrocious reviews (when they are actually reviewed). It doesn't matter what you are trying to make, what matters is what you actually make.
Starship Troopers (the movie) was meant to be a satirical look at war movies (in vein with the original short story). It ended up being an awesome sci-fi war movie with Dina Meyer going topless :p
I fully agree that this is a great game for some mindless fun. But that doesn't mean it is going to get great reviews.
Hell, I love UFO:ET. That thing got pretty crap reviews from most sites (if I recall correctly). Almost all 4x games do as well. Why? They aren't what most gamers are looking for, and in the end, that is what reviews are about.
