This was a very enjoyable co-op experience, but I don't think I would have finished it solo. The pacing is its biggest misstep. RE4 worked as well as it did in large part due to its pacing. It was an action game, but it knew when to slow the hell down and let you explore an area in peace for a bit, so the action never felt monotonous. RE5 makes no time for such things, it's practically nonstop action the whole way through, so before too long I just kinda found myself numb to all the set pieces it was throwing at me.

Still, it is fun to play, and a lot of the level design is pretty great. This is the game you play when you've finished RE4 and just want some more of that combat system.
