Definitely.
Blu-Ray movies increased the sales of the PS3, made Blu-Ray a success and it was a brilliant feature to have. Some games also took advantage of it, while it's not exactly a big deal, it eased pressure on developers to compress or remove content and assets and allowed uncompressed video files which were easier to make (mostly) and looked far better than in-game cutscenes. Blu-Ray bumped up the price of the PS3, but not by too much, it would have made SONY more money instead of losing money.
Cell on the other hand was a mistake.
