Do any of the Halo titles deserve critical acclaim?

[Goddbless]

I think I played the multi-player of Halo 2 the most out of any game ever. However I think the best campaign was in Halo 3. Plus with 4 player co-op the replay value is unreal. I still haven't finished ODST so I can't really talk about that one. Also Halo Wars was ok for what it was but I've played better RTS games on a console like C&C3 or even LOTR:BFME. The only thing that made Halo Wars good at all was the storyline and being to use Halo units in an RTS.
