The worthiness of an MBA is directly linked to the tier (in simple terms, ranking) of the institute offering MBA.
Tier I institutes: like IIMs, XLRI, IMT, ISB, FMS, NITIE, SP Jain etc. you definitely get placed in top companies and get good packages as well.
Tier II institutes: like FORE, NMIMS, Symbiosis & Sinhgad college etc. you may get placed in good companies, if you are bright, dynamic and have good communication skills. If you do not have these skillsets, chances are high that you may line up with students of tier III /IV institutes.
Tier III/IV institutes: The list is really long and ever growing! There is not really any great benefit here, as per my personal experience, many of these MBA students are aligned with other streams of PG education and at times even graduation. However, this MBA might help you in getting promotions at a later stage of your career, but it will definitely NOT set you in a separate league, when getting entry level jobs.
